“Now I would remind you, brothers, of the gospel I preached to you, which you received, in which you stand, and by which you are being saved …” (v1-2). Paul felt it was important to remind the Corinthians believers about the facts of the good news. Jesus the Messiah (God’s anointed ruler) died for our sins “according to Scripture,” and he was buried, raised again, and seen by many people. The gospel is the good news about what Jesus actually did to save us. His death covered our sins, and His resurrection gave us new life.
The story of Jesus’ life, death, and resurrection is “of first importance” (v3). Our sins are forgiven, and we live by His resurrection power.
