​I. The Diagnosis: Dull Hearing (Hebrews 5:11)
Hebrews 5:11 – “About this we have much to say, and it is hard to explain, since you have become dull of hearing.”

Luke 10:27 – “And he answered, ‘You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind, and your neighbor as yourself.’”
​
II. The Symptom: Childish Understanding (Hebrews 5:12-13)
Hebrews 5:12-13 – “For 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, for everyone who lives on milk is unskilled in the word of righteousness, since he is a child.”

3. Milk and moral immaturity

1 Corinthians 3:1-2 “But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready,”
Mohler - “…Spiritual immaturity leads to moral immaturity. Spiritual immaturity leads to believers who live according to the flesh rather than the spirit.”

4. The word of righteousness

III. The Remedy: Discerning Power (Hebrews 5:14)

Philippians 3:15 – “Let those of us who are mature think this way, and if in anything you think otherwise, God will reveal that also to you.”
