Jesus' message always encouraged people to repent. There is no doubt about that. The Bible proclaims that if you believe in Jesus and confess your sins to him, you will be saved. "Apologizing" is a crucial step in becoming a follower of Christ- but it wasn't a preliminary requirement for Jesus' death.
Jesus never said, "I'm very willing to die for you, but not until you say you're sorry." He did quite the opposite. He died for us first. There were no bribes or prerequisites.
One of the criminals sneered insults at him, even while they hung in pain. Jesus could have reminded him that later on that day (while he burned in Hell) he probably would want to take back all that "get yourself down" stuff. Instead, Jesus died for him. Then there was the other criminal. We don't know what sins he committed, but most likely it wasn't something like tax evasion. Whatever crimes he had committed were now being felt by Christ. Instead of making him repent first, he promised him eternal life.
Now, here I am.
Why do I consider myself so worthy, that I would want someone to tell me they are sorry before forgiving them? Why would that be of any consequence to me? Because I somehow believe that it will make me feel better. I believe they owe it to me. I think I deserve certain things but in reality, I don't deserve anything.
Jesus never made me apologize for the future sins I'd commit. He died for me first. Some people will never apologize for their sins. They will die never appreciating the suffering of Christ. They will go to their graves mocking him. He died for the people who will always ignore him, as well as those who love him. Only after failing in relationships with other people, can I finally see how beautiful that is. He gave us the gift of free sacrifice without any preconceived notions of equality. There was no equal trade between Christ and I. He died even while the scale tipped completely in my favor. Let me forgive as you have, Lord.
"But God demonstrates his own love for us in this: while we were still sinners, Christ died for us."
