Now after John was put in prison, Jesus came to Galilee, preaching the gospel of the kingdom of God, and saying, “The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel.” Mark 1:14–15
Christians love the gospel. We dedicate our lives to spreading the gospel message to our friends and neighbors and even to every corner of the earth.
But what is the gospel? What is it’s message? Paul tells us very clearly in his letter to the Corinthians.
