The part where Jesus urged us to forgive our enemies:
Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.” To the contrary, “if your enemy is hungry, feed him; if he is thirsty, give him something to drink; for by so doing you will heap burning coals on his head.” Do not be overcome by evil, but overcome evil with good.
Romans 12:17-21
Jesus, in the entire New Testament up to his Crucifixion, was talking exclusively to Jews. Nobody else. Jews. That's it.
Jews back then wanted a Fighting Messiah to come and wage War against the Romans and kick their asses.
Jesus told them that just wasn't going to happen and that they needed to pursue peaceful ways.
Good idea. Taking on the Roman Army wouldn't have been real smart back then.
But you're stupid, so you wouldn't know that.
AFTER Jesus was Resurrected, he began to speak to ALL of humanity to an extent.
Before then.... He was speaking ONLY to Jews and ONLY to Israelites
