1 Brothers and sisters, I could not address you as people who live by the Spirit​ ​but as people who are still worldly—mere infants in Christ. 2 I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready.3 You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere humans? 4 For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not mere human beings?—1 Cor. 3:1-4 (NIV)
​Up until the death of Jesus​, the people would follow after certain Rabbis, the great teachers of religion in that time. These Rabbis taught the Old Testament laws and rules, as well as those who taught idol worship. Now there was a new plan of salvation instituted with the death and resurrection of Jesus. In a sense, it is understandable that the people, at that time, would have been inclined to follow the teachers and not just their teaching. Paul is telling the Corinthians that they aren’t yet able to understand the message. They must first learn that it is the message that is important and not the messenger. Until they understand this and have accepted Jesus as their Savior and Lord, he is not able to teach them in more depth. We still have the same thing happening in our society today. We have people who are misled and think that the messenger is the savior, thus we have cults and incidents such as Jim Jones, where people follow their leaders even unto death. Paul was concerned that the people in Corinth would turn back to the law or false religion. He wanted to be able to get them grounded in the faith by teaching them about living a Holy life after being saved, so that they, in turn, could make disciples of others. Today, we have many people who are saved and then become unsatisfied with Christianity because we don’t teach them to live holy lives. They drop out of church because we don’t teach them that living for Jesus is hard, but the joy and the end result is more than worth the effort.
57 But thanks be to God! He gives us the victory through our Lord Jesus Christ.–1 Cor. 15:57 NIV
