Sin is soulish spilled milk. Once accomplished, even at some minimalistic level, sin marks the sinner for the rest of his or her life. He or she cannot go back to the spiritual quality he or she had before. Something is used up which cannot be unused or self-restored. Sin is the indelible stain of the soul.
To deal adequately with sin, the sinner must look beyond his or herself, and beyond anything else that suffers from entropy--something which cannot only jam the dhinni back in the bottle, but can also erase the record of the failure in time. Anything less would not be true restoration. There is nothing that fits that bill except for almighty God, for he alone is not entropic and also supertemporal.
God is willing to both erase the spiritual decay of sin and it's record. He is willing to reset the clocks, as it were, and start again. There is a time he's appointed to do that, and in the meantime, he has graced us with a taste of what is to come. What is necessary to overcome sin and death has been provided by the only source possible and it has been made widely available to all who wish it.
For all who've faced the undeniable conclusion that they are not what they should be, and that they can't do anything about it, there is great news in Christ. He's demonstrated his ability to take away our sin and overcome death. He promises to make anyone who trusts in him to do so new on the last day and take them into eternity without decay. Life without entropy awaits us, what are you waiting for?
