So, where does "Father, forgive them .. they don't know what they're doing" fit into your understanding?
Are you Jesus?
I thought not.
Happy Easter.
Jesus prayed for God not to hold their sin against them but those are the same people who before that had told Pilate “let his blood be on us and on our children. “
They were granted their wish, as these same people were destroyed in the fall of Jerusalem years later.
Jesus said, “Forgive others as you have been forgiven.” That means repentance is required.
