“The Good News is about his Son. In his earthly life he was born into King David’s family line, 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.” Romans 1:3-4
Paul was convinced on the road to Damascus that the good news was the birth of Jesus Christ. When Paul was a Pharisee, he believed in the law and the traditions of the Jews. But when he yielded to Christ, he was separated to the gospel and its ministry. This gospel or good news is the message that Christ died for our sins, was buried and rose again, and now is able to save all that trust in Him. It is the Gospel of God because it originates with God; it was not invented by humans.
The gospel is not a new message; it was promised in the Old Testament, beginning in Genesis 3:15. The prophet Isaiah preached about it in Isaiah 1:18 and chapters 53 and 55. The salvation we enjoy today was promised by the prophets, but they did not fully understand all that they were preaching and writing. “This salvation was something even the prophets wanted to know more about when they prophesied about this gracious salvation prepared for you. They wondered what time or situation the Spirit of Christ within them was talking about when he told them in advance about Christ’s suffering and his great glory afterward.” (1 Peter 1:10-11) This Good news was for us, but the prophets wanted to know more about it, but God had the perfect timing. God knew when this was to come about. “They were told that their messages were not for themselves, but for you. And now this Good News has been announced to you by those who preached in the power of the Holy Spirit sent from heaven. It is all so wonderful that even the angels are eagerly watching these things happen.” (1 Peter 1:12) Paul’s experience on the Damascus Road was in God’s timing. Paul was to bring this Good News to the Gentles.
