Monergism

Forgiveness flounders because I exclude the enemy from the community of humans even as I exclude myself from the community of sinners. But no one can be in the presence of the God of the crucified Messiah for long without overcoming this double exclusion - without transposing the enemy from the sphere of monstrous inhumanity into the sphere of shared humanity and herself from the sphere of proud innocence into the sphere of common sinfulness. When one knows that the torturer will not eternally triumph over the victim, one is free to rediscover that person's humanity and imitate God's love for him. And when one knows that God's love is greater than all sin, one is free to see onself in the light of God's justice and so rediscover one's own sinfulness.

Christian, you know that one sin you have repented of but still gnaws at your conscience? Jesus fully absorbed God's just wrath for it, and as such, He remembers it no more.... He will not to treat you as you justly deserve. It has already been dealt with. Once you've been granted His forgiveness, believe His promise! (Rom 8:1)

"Christ by his intercession answers all bills of indictment brought in against the elect. Do what they can, sin, and then Satan, accuses believers to God, and conscience accuses them to themselves; but Christ, by his intercession, answers all these accusations."
-Thomas Watson
