Heb 5:11-14 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.
This is one of the most important Scriptures for professing Christians and churches in our day. And yet most are ignorant of what the Lord is telling us here. This ignorance (or downright disgust) of these truths are causing all kinds of suffering to Christ’s people in so-called churches.
At best, most people who claim to be Christians are, as the Apostle says here, children. They of course fancy themselves to be quite the mature saints but the fact is that they cannot handle solid food. They don’t have teeth or the capacity to digest. Infants in diapers.
But that is at best. At worst, and I suspect far more common, is the reality that many if not most of them are not born again at all. God’s Word is therefore foolishness to them. And if that sounds unplausible to you, then just read on into Hebrews 6 because what the Apostle is doing here at the end of chapter 5 is introducing us to the topic of apostacy.
