If Peter did not preach Paul's grace gospel, why does he speak of grace, the cross, and of faith and hope in his epistles?
QUESTION:
Read 1 Peter 1:10-12, 14-21. Within the first chapter of Peter’s first letter, he speaks of the grace of God that would come to them. Not only did He speak of this, but He also spoke of faith and hope they would have by being in God. He also referred to the cross of Christ when he said his recipients were redeemed with precious blood, as of a lamb unblemished and spotless, the blood of Christ.
It sounds to me that Peter is preaching the grace gospel since he spoke of the grace that would come to the Jews and the blood of the cross being shed for them which is what Paul preached day to day.
Peter was the apostle to the circumcised and Paul was the apostle to the Gentiles, Galatians 2:8. This does not mean the gospels they preached were different, it only means their assignments were different.
Once again, these words were written by the apostle you said never preached the grace gospel of Paul. Please explain.
ANSWER:
Your questions are valid. I appreciate you asking. Let me take them one at a time and clarify with my perspective.
In Luke 20 you ask which gospel was Jesus' preaching.
The answer is that He was preaching the only gospel that existed at that time, the gospel of the kingdom that pertains to the Jews. Paul has not yet been saved, so God’s revelations concerning the grace gospel have not yet been made known.
