Psalm 88:15-16 i am afflicted and ready to die from my youth up: while I suffer thy terrors I am distracted. Thy fierce wrath goeth over me: thy terrors have cut me off.
Sin causes death and its consequent suffering during a short life. The Psalmist is afflicted and ready to die. He is suffering the terrors that come from God. The Law is doing its work on convicting of sin and bringing about repentance so that we might turn to God and believe the Gospel as our only hope of salvation.
The terrors are called God’s terrors, assuming they come from God. God uses the devil, the world, and our own flesh to afflict. God does no evil and He could stop it, but He uses it to bring about a good result, our faith and salvation. The terrors of God’s wrath are real, but the love of God is more powerful. We turn to the Cross and see the wrath poured out upon our sin. We believe and are saved from wrath and terror.
