Jesus never excused sin; he actually upped the ante. In the Sermon on the Mount, Jesus redefined sin that makes me, and everyone I come in contact with, guilty of murder and adultery. When Jesus meets with the woman at the well in the Gospel of John, he calls out her behavior as sin. And when the woman caught in adultery later in the same gospel is alone with Jesus after all of her accusers have left, Jesus tells her, “Go now and leave your life of sin.”
But what compels these women to leave their lives of sin is not judgment and rejection and a hard-line stance, but rather a radical, life-altering experience of love. They realize that, contrary to their culture, they are so much more than their sin, and that they are loved even in their sin.
What is so hard for me to wrap my heart around is that Jesus knew that Judas was not going to repent, and yet he still opened the door of hospitality to Judas till the very last minute. Till the very last minute Jesus was inviting Judas into love; Jesus never stopped inviting Judas into love.

Camp's reflections upon and honest questions about Jesus' transformative love for strangers and for his enemies are important. In recent days some Christian leaders have even begun to claim Jesus only really fellowshipped with those who were responsive, repentant, and were already following him. This is a pernicious idea that serves only to give our sinful hearts the excuse it needs to marginalize those with whom we disagree. "If Jesus only had fellowship with repentant people, then I am justified in doing what Jesus did. I can exclude those who don't meet {my} the criteria for a truly repentant person." Of course this is wrong; but if we don't take care it's where many of us live.

The whole of Camp's post is well worth taking the time to read and consider.
