Jesus spoke,

"And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem." - Luke 24:46-47

Peter preached of Christ’s suffering, death, burial, and resurrection to Jews from all nations on the Day of Pentecost at Jerusalem. He then preached of repentance and remission of sins in Jesus name:

"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost." - Acts 2:38
