What the Bible says about Children in the Faith
(From Forerunner Commentary)
This is similar to what Paul says in Hebrews 5:12. Because they were still children in the faith, he has to speak to them as if they were spiritual babies. This happens all over—it is not confined to Corinth or to the Hebrews, wherever they were. It certainly is applicable to us.
