Read 1 Corinthians 3:3 Using Other Translations
For ye are yet carnal: for whereas there is among you envying, and strife, and divisions, are ye not carnal, and walk as men?
for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way?
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?
