11 About this we have much to say, and it is hard to explain, since you have become dull of hearing. 12 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, 13 for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. 14 But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. (5:11-13)
Ill Prepared: Having begun a discussion on the priesthood of Melchizedek, he expressed concern, knowing what he had to say was deep and that his audience was not able to understand what he was saying. He was alarmed that they were so immature at this point in their spiritual journey or had fallen back in their faith that they had no foundation for grasping the truths he was about to reveal.
Admonition: As a result, he moves from exhortation to scolding his readers because he expected them to be: (1) teachers and not students, (2) familiar with the fundamentals of the faith, (3) grasp what they had heard at a deeper level, and (4) able to apply the Word to their lives. Unlike the Gentiles, they should have been able to deal with and apply the principles of their faith to daily living.
Challenge: Where are you in your spiritual journey? Are you gleaning truths from scripture with the help of the Spirit? Are you a student or teacher?
To me, growing into spiritual maturity is becoming less self-conscious and more God-conscious. Mark Batterson
