Paul's desire to go to Corinth was only overshadowed by his desire to stay in Ephesus. Paul explained that in Ephesus, God had opened a door for the gospel and his opportunities to teach and preach were numerous and effective; however, he also explained that in Ephesus there was also a great deal of adversity. The lesson for us; adversity to the gospel should be expected, and we should never run from an opportunity to share Christ because of it!
