I was unable to teach you difficult concepts, because you were controlled by your self-directed nature, as evidenced by your quarreling about which leader you should be loyal to.

1 Corinthians 3:1-4

3 My fellow believers, when I was with you previously, I was not able to teach you as I would teach people who are controlled by the Holy Spirit {whom the Holy Spirit controls}. Instead, I had to teach you as I would teach people whom their self-directed nature controls. I taught very simple concepts to you who had recently believed in Christ, as a parent would speak very simple words to a baby. 2 I did not teach you things that were difficult for you to understand, just like a woman does not give her baby solid food that the baby cannot chew and digest. And just like a woman ◄gives her baby milk/breast-feeds her baby►, I taught you simple spiritual concepts, because at that time you were not able to understand difficult things. And you are still not able to understand difficult concepts, 3 because you are still controlled by your self-directed nature. Some of you are jealous and quarreling. ◄That shows that your self-directed nature is controlling you!/Does not that prove your self-directed nature is controlling you?► [RHQ] It shows that you are acting like unbelievers act. 4 By some of you saying, “I am loyal to Paul,” and others saying, “I am loyal to Apollos,” ◄you show that you are acting like unbelievers./does not it show that you are acting like unbelievers?► [RHQ]
