When Paul first came into Corinth, he was alone for the first time since he began his missionary journeys. He had been chased out of Macedonia and had to separate from the rest of his companions. He boarded a ship and sailed down to Athens, preached there, then moved into Corinth. For whatever reason, Paul was fearful and felt very alone.
When Timothy and Silas finally joined Paul in Corinth, Luke says that “Paul was occupied with the word” (Acts 18:5). This is interesting because Paul told the Corinthians that, when he first came, he “decided to known nothing among you except Jesus Christ and him crucified” (1 Cor. 2:2). Paul was very, very focused on Jesus and the cross. In fact this was his sole focus.
Paul makes it clear that Paul came to Corinth in weakness and in fear and much trembling. Though he later says that he imparted wisdom to the mature, at first his message was not shrouded in lofty speech and wisdom. Rather, it was in demonstration of the Spirit and of power “so that your faith might not rest in the wisdom of men but in the power of God” (1 Cor. 2:5).
Sometimes we get so troubled with getting our message right that we lose focus on Jesus and the cross. The irony is that the message ends up getting diluted. Paul was more interested in remaining focused on Christ and him crucified than he was getting his speeches right. Because Paul maintained this focus, he was able to witness by way of demonstration of the Spirit and of power. This is what transformed people in Corinth. Where the Spirit of God is at work, there is life!
