1. The Gospel is the Good News of Jesus. God sent out Paul to preach the Good News. Paul wrote a letter talking about the Good News to the believers in Rome.

Romans 1:

1 This letter is from Paul, a slave of Christ Jesus,  chosen by God to be an apostle and sent out to preach his Good News. ² God promised this Good News long ago through his prophets in the holy Scriptures. ³ The Good News is about his Son. In his earthly life he was born into King David’s family line,⁴ and he was shown to be the Son of God when he was raised from the dead by the power of the Holy Spirit. He is Jesus Christ our Lord. ⁵ Through Christ, God has given us the privilege and authority as apostles to tell Gentiles everywhere what God has done for them, so that they will believe and obey him, bringing glory to his name.
