Head Knowledge Won't Save You: Moving From Agreement to Surrender (Hebrews 6:1–8)
A study through Hebrews 6 from Moses Lake Bible Church
If you were watching the 1988 Summer Olympics in Seoul, you remember the moment. Canadian sprinter Ben Johnson exploded out of the blocks and ran the 100 meters in 9.79 seconds, a new world record. He took his victory lap. He collected the gold medal. The whole world praised him as the fastest man alive.
Three days later, it was gone.
The judges had the blood test results back, and they showed anabolic steroids. Johnson was publicly stripped of the medal, his record was erased, and his rival Carl Lewis rightfully received the gold. Johnson went home disgraced and banned. When he finally returned to competition in 1993, he failed another drug test and was banned for life.
Here is why that story matters for Hebrews 6. On the outside, everything about Ben Johnson looked like a winner. The race, the lap, the medal. But the judges looked past the appearance. They saw the inside. They brought what was hidden into the light and said, in effect, "This man did not obey the rules. This man is not the winner."
Hebrews 6 tells us that God sees the same way. He sees the inner truth, and he has promised that the truth will be brought into the light. The question the chapter presses on every one of us is simple and uncomfortable: is my faith real on the inside, or does it just look right from the stands?
First, a Word About Why People Are Leaving
Before opening Hebrews, our pastor shared a few takeaways from a book called The Great Dechurching by Jim Davis and Michael Graham. The authors studied why so many people across Western culture have walked away from church, especially since 2020. Not every conclusion in the book landed, but several were worth passing along.
Our primary concern as a church is not a comfortable building, good air conditioning, or good coffee. Our primary concern has to be the gospel, because apart from the gospel, people are lost. Shallow religious entertainment has no lasting value; it does not fill the God-sized hole in a person's heart, and people eventually get tired of it. Legalistic, works-based religion fails too, because it never brings anyone into a close relationship with God. And hypocrisy and double standards have driven people away for as long as the church has existed, because the church has always been full of imperfect people. Just look at us.
The takeaway was to stick to the real, original gospel of the New Testament. Don't add to it. Don't subtract from it.
The book also pointed to the deep division in our country, which is dividing families and churches alike. Many parents in our own congregation grieve that their adult children won't talk with them about faith because they've been labeled a "Bible thumper" or a far-right wacko. How do we get past that?
Listen. Hear. Appreciate what they have to say on its own merits. Find something good to say about it. And then be very, very careful, and very prayerful, with criticism. That doesn't mean accepting bad ideas. It means recognizing that whacking people over the head with the truth feels good but isn't very effective. As our pastor admitted, he has been guilty of it plenty of times.
The rule is always truth in love. And if you think you can share truth without first letting the Holy Spirit lead the way, it isn't truth in love no matter how nice you are, because none of us can love in a truly unselfish way on our own.
Finally: invite people. Every kind of church in every part of the country found the same thing. Anytime you see someone at work, at the grocery store, at the gas station who is angry, hurting, or depressed, that is an open invitation to say, "I know some place that might help. I know a guy, Jesus, and I know a family." Be inviting in every way, all the time.
Evangelism is where it starts. Then comes discipling, which is simply walking beside someone and saying, "I'm still learning this too. I'm a little ahead of you. Let's do this together." That maturing of faith is exactly where Hebrews 6 picks up.
Head Knowledge Is Not Saving Faith
Hebrews 5 ended with a warning: "Solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil." Nobody ever sits still spiritually. You are either moving closer to God or drifting further away.
The danger the writer keeps circling back to is stopping at intellectual assent, that indifferent "Yeah, sure, I agree with that." Head knowledge is not saving faith. They are very different things. Passive agreement eventually loses steam because there is no real meat to it, no traction. It cannot produce the kind of sincere trust that says, "I will do it simply because you said so, Lord."
Think of the twelve spies Moses sent into the promised land. Ten of them came back with accurate facts: giants, huge armies, fortified cities. Everything about the situation argued against going in. Only two had the kind of heart-level faith that could say, "We're going in for one reason. God said to, and he said he'd be with us." Head knowledge does not produce that courage.
Or think of Simon Peter. Jesus finishes teaching from Peter's boat and tells the professional fisherman to let down his nets in broad daylight, the worst possible time to fish. Peter's answer is pure head knowledge: "Master, we've toiled all night and taken nothing. But at your word, I will let down the nets." Then the nets fill until they're breaking and two boats begin to sink. And Peter falls at Jesus' feet: "Depart from me, for I am a sinful man, O Lord." In a single moment, "I know you're a great teacher" became a heart surrendered to the Lord.
Jesus describes the other side of that coin in Matthew 7:21–23. "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven." Many will point to prophecy, deliverance, and mighty works done in his name, and he will say, "I never knew you." Notice who he is talking about. Not people who openly reject him. People who insist, "I am one of your followers." In our day, he would be speaking to people sitting in his churches, wearing the clothes, talking the talk, living the lifestyle as best they can, but without a heart truly surrendered to him.
That kind of surrender produces something the world cannot fake: true biblical discernment, a Christian worldview shaped by constant time in God's Word and yielding to the Holy Spirit. It moves us from emotional decision-making to Spirit-led decision-making. This matters more than ever, because so much of what we consume online is training us to react emotionally, and the enemy wants us as emotional decision-makers. That is putty in his hands. He can manipulate, turn, and twist it. Spirit-led decisions often won't line up with what makes sense to the world. Just ask those two spies.
Leave the RV: Six Foundations to Move Beyond
"Therefore let us leave the elementary doctrine of Christ and go on to maturity," Hebrews 6:1 begins, and then lists six things: repentance from dead works, faith toward God, instruction about washings, laying on of hands, resurrection of the dead, and eternal judgment.
At first glance that sounds alarming. Leave repentance? Leave faith in God? But remember the audience. This letter was written around AD 68 to Jewish believers whose entire foundation was the Old Testament. The main message of Hebrews is that Jesus is preeminent over everything. The secondary message is that you have to move out of the shadows of the old covenant, because everything in it was pointing to him.
Picture a family who buys a piece of land and lives in an RV while they build the house. Then the house is finished, and they stay in the RV. RVs are tight. The sinks are plastic. Things break constantly. The house is right there. What are you waiting for? Leave the RV. Go to the house. It's finished. The new covenant is here.
Here is what each of the six looks like when you move into the house.
Repentance from dead works. The old covenant offered half of repentance: turn from evil and toward God's law. But there is no Jesus in that, so there is no salvation in it. The blood of goats and bulls was always temporary, and now it does no good at all. Beginning with John the Baptist, repentance became complete in Christ. "No one comes to the Father except through me" (John 14:6).
Faith toward God. Believing in God alone is no longer enough. Jesus is the linchpin, the non-negotiable. Peter's Pentecost sermon was "Repent and be baptized, every one of you, in the name of Jesus Christ." Before the council he said, "There is no other name under heaven given among men by which we must be saved."
Washings. Every Jewish home had a basin for ceremonial cleansing, and there were rituals for nearly everything. Those washings were always temporary, and now they are ineffective. Ezekiel 36 had already pointed forward: "I will sprinkle clean water on you… I will give you a new heart and a new spirit… I will put my Spirit within you." Titus 3 tells us we are saved "by the washing of regeneration and renewal of the Holy Spirit." Jesus himself said we must be born of water and the Spirit.
Laying on of hands. This isn't about elders praying for the sick. In the sacrificial system you laid your hand on the animal to identify with it and transfer your guilt before it was killed. Our identity is now in Jesus, by the indwelling Holy Spirit who baptizes us into union with him. As the pastor put it, we no longer have to go with the goat plan.
Resurrection of the dead. The Old Testament gives only a dim, incomplete picture of life after death, like looking through dirty water. The New Testament makes it one of the most detailed doctrines we have. "I am the resurrection and the life," Jesus told Martha. "Whoever believes in me, though he die, yet shall he live." First Corinthians 15 describes the resurrected body, and 1 John 3 promises, "We shall be like him."
Eternal judgment. Ecclesiastes goes about as far as the Old Testament does: fear God, keep his commandments, for God will bring every deed into judgment. The New Testament brings clarity and hope. "There is therefore now no condemnation for those who are in Christ Jesus" (Romans 8:1). All judgment has been given to the Son, and "whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life" (John 5:24).
Six shadows, six symbols that served their purpose for a season. Let go of them completely and take hold of the mature, perfect reality found only in Jesus, the perfect sacrifice and perfect redeemer.
The Scary Verses, Read Carefully
Then come the verses that unsettle so many readers. "It is impossible, in the case of those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, and then have fallen away, to restore them again to repentance" (Hebrews 6:4–6).
On the surface it sounds like you could accidentally lose your salvation by being foolish. But Scripture interprets Scripture, and Scripture does not contradict itself. This passage is proof of how much we need the Holy Spirit to understand God's Word. If you've ever thought, "I just cannot get this part," stop. Ask the Lord, "Show me your truth. Show me what you need me to know today." Spiritual understanding comes by the grace of God.
Look at how the writer describes these people. They have been enlightened, meaning taught, presumably by the apostles themselves. They have tasted the goodness, meaning they have lived in fellowship with true believers. They have "shared in" the Holy Spirit, and in the original language that word means association, not possession. The Spirit was around them, not within them. They had heard the Word and seen miracles. They believed to some degree. But it was head knowledge that never governed their lives.
In other words, the writer is not speaking to the saved. He is speaking to the unsaved inside the church, people who have every advantage and every reason to go further, yet have never surrendered. His warning is urgent: come to Jesus now, because coming to church, doing the stuff, and putting on the act doesn't save you. If you walk away from all that light back to the world, it will be fatal.
Then he gives an illustration any farmer understands. Land that drinks the rain and produces a useful crop receives God's blessing. Land that produces thorns and thistles is worthless and headed for burning. Everyone who hears the gospel is the earth. The same rain falls, the same seed is planted, the same sun shines. Some of that growth is rooted in God and bears good fruit. Some of it is a weed. And anyone who gardens knows that a weed can look green and healthy right up until it grows up and shows what it really is.
This is not a message to frighten believers. It is an invitation to those who are pretending, trying hard to look like everyone else, quietly wondering why they never quite fit, always feeling like they're on the outside looking in. The danger is that if you stay in that mode long enough, it starts to feel normal. "I guess this is all there is." It's an imitation, a shadow of the real thing.
The real thing is a heart that says, "I will do what you say because you said it, and that's enough. I don't care if it looks crazy to the world."
Our pastor gave a personal example. His dream, like most of ours, is to retire someday. But his rule is that he goes nowhere until God says he can. He can ask. He just refuses to pretend God said yes. "I will do what you say, because I know your plan is better."
How Faith Is Rekindled
Hebrews will spell this out more fully in chapter 10, but the road back for those who have grown dull of hearing has three steps.
Draw near to God. Surrender, and let his Word move from your head into your heart.
Wait with expectation. Nothing happens except what God allows. When horrible things happen, when nations go to war or the ground shakes, we wait with anticipation, knowing he is God and he is sovereign. The comfort in that is knowing we belong to him.
Stir one another up. We are called to lift each other up with the Word of God, the Spirit of God, and brotherly affection. Hurting people are not only out in the community; they are sitting in our pews.
That last point came with a story. Just days before this message, the pastor was hiking in the dark with a friend when the friend's dog ran onto the road and was killed. This was the same friend he had once badly botched a gospel presentation with, a conversation that ended in anger. The next day they held an impromptu burial, shared a little Scripture, and prayed. There was nothing to fix the grief. There was only one more gentle invitation: I know you're hurting, and there is peace to be found in Jesus.
The Takeaway
Hebrews 6:1–8 is not about believers losing their salvation. It is about people who look like winners from the stands but have never let the truth move from the head to the heart. God sees the inside, and he has promised the truth will come to light.
So here is the honest question to carry into the week. Is there anything in your faith that is still just agreement? Is there any part of your life where you've said "yes, that's true" but never "yes, Lord, I'll do it because you said so"? Ask him to show you. Then take one more step.
Our pastor likes to end on a high note, and he admitted this one didn't quite get there. But he found it anyway: there's peace in the Lord. That's the high note.
