Thy Strong Word — Hebrews 5:11-6:20: Quit Being Babies

“But you still need milk, not solid food.” That’s the sharp rebuke in Hebrews 5. Then comes the warning that falling away from the faith is real, serious, and deadly. The author warns against stagnation, urging Christians to grow beyond the basics. Yet, the warning deepens—some have fallen away and cannot be restored. How do we understand this, and what about the sure hope in God’s promises? Hebrews challenges and reassures us in this tension.

The Rev. David Boisclair, senior pastor at Our Redeemer Lutheran Church in Overland, MO, joins the Rev. Dr. Phil Booe to study Hebrews 5:11-6:20.

For centuries, God spoke through prophets, in visions, through fire and thunder on Mount Sinai. But now, Hebrews tells us, He has spoken fully and finally in His Son. This book isn’t just another epistle—it’s the key that unlocks the Old Testament, revealing how everything was always pointing to Christ. The prophets, the angels, the priesthood, the sacrifices—all find their fulfillment in Him. Over the next several weeks, we’ll walk through Hebrews, uncovering its depth, its urgency, and its breathtaking vision of Jesus as the great High Priest, the perfect sacrifice, and the One who is greater than all who came before. If you’ve ever wondered how the Old and New Testaments connect, how the shadows become substance, this is the book to study.

Thy Strong Word, hosted by Rev. Dr. Phil Booe, pastor of St. John Lutheran Church of Luverne, MN, reveals the light of our salvation in Christ through study of God’s Word, breaking our darkness with His redeeming light. Each weekday, two pastors fix our eyes on Jesus by considering Holy Scripture, verse by verse, in order to be strengthened in the Word and be equipped to faithfully serve in our daily vocations.

Hebrews 5:11-6:20

Warning Against Apostasy

¹¹About this we have much to say, and it is hard to explain, since you have become dull of hearing. ¹²For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, ¹³for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. ¹⁴But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.

6 Therefore let us leave the elementary doctrine of Christ and go on to maturity, not laying again a foundation of repentance from dead works and of faith toward God, ²and of instruction about washings,^[a] the laying on of hands, the resurrection of the dead, and eternal judgment. ³And this we will do if God permits. ⁴For 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, ⁵and have tasted the goodness of the word of God and the powers of the age to come, ⁶and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt. ⁷For land that has drunk the rain that often falls on it, and produces a crop useful to those for whose sake it is cultivated, receives a blessing from God. ⁸But if it bears thorns and thistles, it is worthless and near to being cursed, and its end is to be burned.

⁹Though we speak in this way, yet in your case, beloved, we feel sure of better things—things that belong to salvation. ¹⁰For God is not unjust so as to overlook your work and the love that you have shown for his name in serving the saints, as you still do. ¹¹And we desire each one of you to show the same earnestness to have the full assurance of hope until the end, ¹²so that you may not be sluggish, but imitators of those who through faith and patience inherit the promises.

The Certainty of God’s Promise

¹³For when God made a promise to Abraham, since he had no one greater by whom to swear, he swore by himself, ¹⁴saying, “Surely I will bless you and multiply you.” ¹⁵And thus Abraham,^[b] having patiently waited, obtained the promise. ¹⁶For people swear by something greater than themselves, and in all their disputes an oath is final for confirmation. ¹⁷So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath, ¹⁸so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us. ¹⁹We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain, ²⁰where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek.

Rev. Dr. Phil Booe

Native North Carolinian Rev. Dr. Phil Booe serves pastor of St. John Lutheran Church of Luverne, MN, and host of Thy Strong Word on KFUO Radio. His parishioners probably think he can’t teach Bible study without a mug of coffee in his hand, and he’ll always be happy to eat a plate of sushi. When he’s not shepherding his flock or teaching on the radio, you might find him watching bad movies from the 50s, 60s, and 70s, and especially binging RiffTrax and MST3K episodes. Some day he’d love to travel to the Lutheran homeland in Germany, but for now he spends time in Minnesota with his wife, son, daughter, and cat, and looks forward to Holy Week every year.
