1. By this gospel you are saved (1-2)
The church in Corinth had many complicated problems, and in this letter Paul had written about many of these in detail. Most of us have problems. But if we have the gospel in our hearts, every problem is an opportunity to grow in the inner person. So Paul turned away from the problems and pointed to the risen Christ and his gospel, the solution to every problem. If we hold firmly to his word we are saved. This is his promise.
2. Of first importance (3-4)
Christ died for our sins, was buried and was raised on the 3rd day. This event is the climax of God's redemptive history. It is the turning point of human history. Jesus' death and resurrection defeated the power of sin and death and set us free from slavery to the devil. When we receive this gospel and believe it in our hearts, we are saved. This is God's grace. It is the turning point of our lives.
Application: Lord, I believe that Jesus died and rose again for me. Thank you for providing a way for me to come to you.
One Word: Christ Jesus died and rose for me
