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 a kind of supplemental post to the one I wrote Monday, But I Just Want to Think Good About Everyone. What the Apostle is saying here is that those kind of people are at best babies in the faith. I say at best because they may well not even be saved at all.
Many professing Christians are dull of hearing God’s Word. You can’t even hardly talk to them about God’s Word. They don’t get it. They are dull and deaf to truth. And they may have been professing Christians for years and years – some were raised in Christian homes and cannot remember a time when they weren’t “Christians.”
But something happened. They kept sucking on their bottles. They choke on God’s Word that is anything beyond “believe in Jesus and you can go to heaven.” Their “Christianity” consists primarily of traditions handed to them, not from diligent digesting of God’s Word. They are still children.
Now, notice what maturity in Christ entails. It is to have our spiritual senses trained by constant chewing on the meat of the Word in order to be able to distinguish good from evil. Get it? There it is. Boast all they want about how mature they are in Christ, the fact is that they cannot see Satan when he is right in their face. In fact, they are so inept at discernment that this scripture tells us that they confuse good and evil. They will defend the evil one and condemn the righteous.
It is very dangerous to have babies leading local churches. All they can consume is milk and all they can serve up is milk. Everyone who says they are a Christian is to be believed no matter their fruit. Sound doctrine taught in-depth is just to divisive – they choke on it. So they stay in diapers and take many others with them.
