Answer:
The gospel:
In Christianity, the gospel or the Good News, is the news of the coming of the Kingdom of God (Mark 1,Mark 1:14-15). The message of good news is described as a narrative in the four canonical gospels.
The message of good news is described as theology in many of the New Testament letters. It relates to the saving acts of God due to the work of Jesus on the cross and Jesus' resurrection from the dead which bring reconciliation ("atonement") between people and God. The apostle Paul's gospel is of Jesus's death on the cross and resurrection to restore people's relationship with God. It may also include the descent of the Holy Spirit upon believers and the second coming of Jesus. Paul gave the following summary (translated into English) of this good news (gospel) in the First Epistle to the Corinthians,one of his letters to Christians in the city of Corinth.
