Day 152—The Way Forward—From Milk to Maturity

“But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.” — Hebrews 5:14 (ESV)

Every healthy living thing is designed to grow. A newborn baby depends entirely on milk for nourishment, but no loving parent expects that child to remain on a bottle forever. As the child grows, so does the appetite. Milk gives way to solid food, and with maturity comes greater strength, discernment, and responsibility. If a healthy adult were still dependent upon baby food alone, something would clearly be wrong. The same principle applies to the Christian life.

God never intended for His children to remain spiritual infants. The moment we place our faith in Jesus Christ, we are born again into God's family. But birth is only the beginning. The Father desires that we continually grow in grace, deepen our understanding of His Word, and mature into faithful followers who not only know the truth but also live it and teach it to others.

Hebrews 5 calls every believer to examine the condition of his or her spiritual growth. The chapter begins by reminding us of the unique ministry of the high priest. Under the Old Covenant, the high priest was chosen by God to represent the people before Him. He offered sacrifices for sin and dealt compassionately with those who were weak because he himself understood human frailty. Yet every earthly priest shared one common limitation—he was a sinner who first had to offer sacrifices for himself before ministering on behalf of others (Hebrews 5:1–3).

Jesus is altogether different. He did not appoint Himself to this sacred office. The Father appointed Him as the eternal High Priest, not according to Aaron's temporary priesthood, but according to the order of Melchizedek (Hebrews 5:5–6). This priesthood is eternal, perfect, and unchanging. That truth should bring tremendous assurance to every believer.

There is no human mediator standing between us and God. Paul declared, "For there is one God, and there is one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5, ESV). A mediator reconciles two separated parties. Humanity stands guilty before a perfectly holy God because of sin. No amount of religious effort, moral achievement, or personal goodness can bridge that separation.

​Only Jesus Christ—the God-Man—can reconcile sinful people to a holy God. Because He is fully God, He alone is perfectly righteous. Because He became fully man, He willingly became our substitute, bearing our sins upon the cross. His sacrifice was once for all. Nothing can be added to it. Nothing can improve upon it.

Salvation is received entirely by grace through faith in Jesus Christ. He alone is the Way, the Truth, and the Life (John 14:6). Every believer stands accepted before God because of Christ's finished work.

The writer then reminds us that Jesus fully understands our struggles because He entered into our humanity. "In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears" (Hebrews 5:7, ESV). These words remind us of Gethsemane, where our Lord prayed with deep anguish as He submitted Himself completely to the Father's will. Though Jesus was always sinless, He willingly experienced suffering, rejection, temptation, grief, and physical pain. Hebrews says He "learned obedience through what he suffered" (Hebrews 5:8, ESV). This does not mean He moved from disobedience to obedience. Rather, through His earthly life He experienced obedience in every circumstance, perfectly fulfilling the Father's redemptive plan.

Because He has walked where we walk, He knows our weaknesses. Because He has suffered, He sympathizes with our pain. Because He conquered temptation without sin, He is able to strengthen us when we are tempted.

Our High Priest is not distant or detached. He understands every burden we carry, every disappointment we endure, every temptation we face, and every tear we shed. He continually intercedes for His people with perfect compassion and unwavering faithfulness.

Then, almost without warning, the writer changes direction. Instead of continuing his teaching about Christ's priesthood, he pauses to address a serious problem among his readers. "About this we have much to say... since you have become dull of hearing" (Hebrews 5:11, ESV). The problem was not a lack of intelligence. It was a lack of spiritual appetite. They had become spiritually sluggish. They had heard God's truth repeatedly, yet they were no longer responding with eager hearts. Instead of progressing toward maturity, they had become stagnant.

The writer says that by this time they ought to be teachers, yet they still needed someone to teach them the elementary truths of God's Word (Hebrews 5:12). What a sobering picture. There is a difference between growing older and growing spiritually. A believer may attend church for decades and yet remain spiritually immature if God's Word is never put into practice.

Milk represents the foundational truths of the Christian faith—the wonderful message of Christ's death, burial, resurrection, forgiveness, and new life. Every believer begins there. But God never intended us to remain there. He calls us to feast upon the deeper truths of Scripture, learning not only what Christ has done for us but what He is doing for us now as our risen Lord and eternal High Priest.

Spiritual maturity is not measured merely by biblical knowledge. It is measured by biblical obedience. Hebrews says mature believers have "their powers of discernment trained by constant practice to distinguish good from evil" (Hebrews 5:14, ESV). Notice those words: "constant practice." Spiritual discernment develops the same way physical strength develops—through consistent exercise. As we daily read God's Word, meditate upon it, memorize it, pray through it, and obey it, the Holy Spirit trains our hearts to recognize truth from error and wisdom from foolishness.

Dr. Tony Evans wisely compares this process to eating. Chewing food without swallowing it accomplishes nothing. Likewise, hearing sermons, attending Bible studies, and reading Scripture without applying God's truth leaves us spiritually weak. God's Word must be internalized before it transforms our lives. When His truth shapes our thinking, we begin making Word-driven decisions instead of circumstance-driven decisions. That is the goal of Christian maturity. God is not merely filling our minds with information. He is transforming our hearts into the likeness of Christ.

So ask yourself today: Am I still living on spiritual milk, or am I growing through the solid food of God's Word? Do I simply read Scripture, or do I meditate on it, memorize it, obey it, and allow it to shape my daily decisions? Am I becoming more discerning, more faithful, more compassionate, and more useful in God's kingdom?

Growth does not happen accidentally. It requires intentional time with the Lord. The same Savior who redeemed you also desires to mature you. Your Great High Priest continues to intercede for you, teach you through His Spirit, and strengthen you through His Word. As you remain close to Him, your faith will deepen, your discernment will increase, and your life will increasingly reflect the character of Christ.

Today, commit yourself anew to God's Word. Feed upon it daily. Practice it faithfully. Share it generously. As you do, you will discover the joy of growing from spiritual milk to spiritual maturity, becoming the man or woman God created you to be.

Prayer:
Father, thank You for giving me Jesus, my perfect High Priest. Create within me a hunger for Your Word and help me grow into spiritual maturity. Teach me to obey what You reveal and to live each day in a way that honors Christ. In His name, Amen.
