1 Corinthians 3:1-2

1My Christian friends, I could not teach you as I would teach people who have God's Spirit. I had to teach you as people who belong only to this world. You were like little children who could not understand the message about Christ very well.

2I had to teach you things that were easy to understand, like a mother gives milk to a baby. You were not yet ready to receive proper food. And you are still not ready to receive God's complete message!
