1 Corinthians 2:3 (KJV 1900)
3 And I was with you in weakness, and in fear, and in much trembling.
We do not typically think of the great apostle Paul as being fearful, and yet when he was in Corinth he was with them in fear and trembling. In Acts 18:9 the Lord Jesus spoke to Paul in a vision and told him, “Be not afraid, but speak, and hold not thy peace.” What was Paul afraid of? The passage does not tell us specifically, but it appears he was fearful of the response to the words of the cross he was speaking.
Paul was opposed by the Jews in Corinth and the message of the cross was blasphemed. These were men out for blood (Just as Paul had been in his earlier life before believing). He knew what they could do to him. Even the Greeks were antagonistic. They beat Sosthenes, and he was the chief ruler of the synagogue (Acts 18:17).
Paul was with the Corinthians in weakness. He knew he could not preach the cross of Christ in his own power. He needed the strength of the Lord and, in fact, the Lord assured him there were many other believers in Corinth who would be Paul’s encouragement (Acts 18:10). God uses other believers to keep us strong in the Lord. Which is why is it good to stay connected to a local Church–for edification to help us when we walk in weakness, and in fear, and in much trembling.
