“[A]s far as the east is from the west, so far does he remove our transgressions from us” (Ps. 103:12). Have you ever thought about just how far that is? A better way, I think, to envisage the relocation of our sins is to consider that our sins are at the horizon; even though we can see them --- both the ones of the past, the present, and those to come --- we cannot bear (or carry) them anymore. We may feel a lingering guilt for them, because we have not forgotten them, because we can remember them, and we may know that they will inflict us again, and yet we no longer can be brought to task for them. As the horizon recedes as we walk toward it, so our sins are unreachable, unbearable. They rest on Christ.
The other thing that is helpful is to know that God, who knows us better than we know ourselves, has removed sin we do not even know about, failures of which we are not cognizant. What a freeing thought. I cannot come up with a sin he has not already carried away. I may suffer the consequences of my stupidity or waywardness, but it won’t kill me (spiritually, that is). It’s over. Justice has already been done. Jesus fell on the grenade of my sin, and it’s over, and He lives. Thank God.
