We speak often of hell and eternal consequences for sin, but perhaps we give too little attention to God’s action against sin in this world and this life. God’s punishment for sin is sin. His punishment is allowing people to experience the life-stealing, soul-rotting consequences of their sin. He expresses his wrath by allowing them the very thing they want. He does this because when they get the thing they want, it only deepens their destruction. In this way, sin is its own punishment. And in all the world I see nothing more terrifying than this, than the prospect of God allowing people to experience the full impact and weight of their sinfulness. Nothing is more terrifying than God determining that he will no longer restrain the evil within them.
