God's wrath is his righteous resolve never to wink at sin, and finally not to tolerate it. To sum it all up. Dead in trespasses and sins, we are unresponsive to God. What alone alters the human condition is the God who is rich in mercy , the God whose love is oceanic. Mercy is love poured out upon those who do not deserve such love.
Mercy is love forever remembering people who deserve to be forgotten.
Grace is love remaining love, love remaining faithful to itself despite innumerable frustrations. Kindness is love supplying specific need. God's wrath is his love frightening complacent people just because their terror is their only hope. Since God is love, his wrath has to be an aspect of his love. Then if you and I are possessed of any depth and discernment at all we should thank God for every time that God has been angry with us, for his anger is simply a sharpened touch of his love upon us.
