What gospel or good news did the apostle Paul preach? Jesus Christ came preaching the gospel of the Kingdom of God (Mark 1:14). Did the apostle Paul preach a different gospel from the one that Jesus Christ preached?

Here is what Paul's companion Luke, the author of the book of Acts says that Paul preached as recorded in Acts 28:30-31:

"30And Paul dwelt two whole years in his own hired house, and received all that came in unto him, "31Preaching the kingdom of God, and teaching those things which concern the Lord Jesus Christ, with all confidence, no man forbidding him." (KJV)

Yes, the apostle Paul preached the same gospel or good news that Jesus Christ preached--the Kingdom of God. Paul preached the good news of the Kingdom of God, to all that came unto him while he was under house arrest by the Roman Empire. He also taught about the things he had learned from Jesus Christ.

In I Corinthians 15:1, the apostle Paul is reminding the Church of God at Corinth of the gospel he had taught them with special emphasis on the resurrection of the dead. In verses 24 and 25, he describes how Christ will eventually deliver the Kingdom of God to the Father:

24Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. 25For he must reign, till he hath put all enemies under his feet." (KJV)

Yes, Paul did not preach a different gospel from the one that Jesus Christ preached. They preached the same gospel, the gospel or good news of the Kingdom of God.
