Speaking of deals, repentance is a pretty sweet offer, when you think of it. Sin, even the major ones, need not keep us from God nor from eternal life. Just agree with God that sin is evil, ask forgiveness, and purpose to do better, with God's grace. That's repentance.
Jesus died so we could have such a deal. That is to say, the cross is the remedy for sin. Taking on our sins was Jesus' part; belief and repentance is our part of the deal. But there is no remedy for making excuses, for rationalizing and justifying our sinful ways. Just repent - agree with God that sin is wrong. To refuse to do so is to refuse the sweet deal, and to remain trapped in the deadly pit our sins have dug us into.
