1 Corinthians 3:1-2

Living Bible

3 Dear brothers, I have been talking to you as though you were still just babies in the Christian life who are not following the Lord but your own desires; I cannot talk to you as I would to healthy Christians who are filled with the Spirit. ² I have had to feed you with milk and not with solid food because you couldn’t digest anything stronger. And even now you still have to be fed on milk.
