31 Dear brothers and sisters, when I was with you I couldn't talk to you as I would to spiritual people. I had to talk as though you belonged to this world or as though you were infants in Christ. 2 I had to feed you with milk, not with solid food, because you weren't ready for anything stronger. And you still aren't ready, 3 for you are still controlled by your sinful nature. You are jealous of one another and quarrel with each other. Doesn't that prove you are controlled by your sinful nature? Aren't you living like people of the world?
Matthew Henry's Commentary on 1 Corinthians 3:1-3
Commentary on 1 Corinthians 3:1-4
(Read 1 Corinthians 3:1-4)
The most simple truths of the gospel, as to man's sinfulness and God's mercy, repentance towards God, and faith in our Lord Jesus Christ, stated in the plainest language, suit the people better than deeper mysteries. Men may have much doctrinal knowledge, yet be mere beginners in the life of faith and experience. Contentions and quarrels about religion are sad evidences of carnality. True religion makes men peaceable, not contentious. But it is to be lamented, that many who should walk as Christians, live and act too much like other men. Many professors, and preachers also, show themselves to be yet carnal, by vain-glorious strife, eagerness for dispute, and readiness to despise and speak evil of others.
