You’ve seen it happen, probably experienced it yourself. A serious relationship ultimately darkens. But the disappearance of its light is not like the flick of a switch. It’s more akin to the dying of a campfire: dancing flames burn down to collapsing embers. It takes time. After all, you invested some of yourself in that person. You swapped secrets, made memories, relished intimacies. Even if the relationship ended badly, you can’t simply unremember the happy times. So try as you might to move on, to evict that person from your head and heart, they seem to be everywhere. You drive past that restaurant where you enjoyed a meal together; there’s that song on the radio you danced to. With a mind full of memories, and a present pregnant with the past, learning to un-love an ex-love is an ongoing, long-term struggle.
It is not much different when that serious relationship happened to be with a particular sin. Maybe the addiction or the sex or the stealing or the violence—whatever your lover was—ultimately made your life a living hell before you finally severed those bonds. But there is no delete button in your brain that easily eradicates all memories of that sin-to-sinner relationship. For between the hours of pain, there were moments of pleasure. The demons know to coat their lips with sugar, so that later, even when they begin to devour us, we still foolishly taste the sweetness of their kiss. Even more complicated is when, in the very midst of sin, a gift of God is given. For example, children are a gift of the Lord, but what if a man fathers a child with another man’s wife? That son or daughter, the embodiment of their adulterous liaison, is also the embodiment of a divine gift. These situations of sin and repentance and God’s activity therein can get real messy, real quick.
So here is our dilemma: even though we have given up the drugs, or ended the affair, or stopped the stealing—severed the bonds with whatever our ex-sin may be—we ask ourselves, “Have I repented enough? Have I repented sincerely enough? Since I still struggle to un-love the ‘good things’ that happened while I was engaged in that sin, have I repented at all or am I just deceiving myself?”
As I have written about elsewhere (in "I Stab it With My Steely Knife But I Can't Kill the Beast Within" and “I’ve Spent the Better Part of My Life Trying to Kill a Man”), the struggle against sin, any sin, is lifelong. A woman may never shoplift again or a man embezzle from his company again, but the monster of greed that drove them to steal abides in the lair of their heart to their dying day. Repentance is not an occasional emotion, but an ongoing motion. It is the motion of God’s hand, reaching down to grab the old Adam by his neck and shove his head again and again and yet again under the waters of Baptism, that the new man in Christ might arise again and again and yet again. The entire life of believers is one of repentance.
Therefore, drawing lines that demarcate where repentance begins and where it ends is like drawing lines in water. It gets even worse if you start asking quantitative or qualitative questions such as, “Am I repentant enough?” or “Have I shown sufficient contrition?” or “Am I sorry because of what I did or only because I got caught?” Such questions are not only wrong-headed; to demand an answer to them from yourself or others is likely only to drive you to question your repentance, its sincerity, and ultimately whether God has forgiven you in Christ.
Here is the most important point I want to make: Absolution is never a layaway plan, forgiveness you finally get to take home once you’ve satisfied the payment plan with enough acts of repentance. That’s because forgiveness does not originate from repentance; it originates solely from Christ. The father did not forgive the prodigal son because he returned home, said he was sorry for his sins, and was unworthy to be called a son anymore. The father had forgiven his son even while that son was feeding swine in a faraway country. The father had forgiven his son before he saw him a long way off and began running toward him. The father had forgiven his son because he was his son, because he loved him as only a father can. So it is with us. “God was in Christ reconciling the world to Himself,” (2 Corinthians 5:19). The world was absolved on Good Friday. And that forgiveness, given to you in the here and now, is not earned, or allowed, or sweetened, or strengthened, or made more real by your repentance.
Should you repent of the wrong you’ve done? Of course. Should you continue to repent as you struggle to un-love that ex-sin? Of course. You will never repent enough. You will never repent sincerely enough. But forgiveness is not based upon having enough repentance or having sufficiently sincere repentance. Absolution is based upon the atoning work of Jesus Christ. His atonement is enough. His sacrifice was perfectly sincere. His blood covers not only the sin of which you repent, but your imperfect repentance for that sin.
The entire life of believers is one of repentance, but more importantly, the entire life of believers is the life of Jesus Christ, whose love for us is always more than enough.
