How has the Lord covered the daughter of Zion with a cloud in his anger! He has cast down from heaven to the earth the beauty of Israel, And hasn't remembered his footstool in the day of his anger.
Yes, He is a God who loves mankind, who gave His Son upon the Cross for human redemption.  He is a God of mercy, forgiveness, grace and forbearance, but when any man or any nation has fully demonstrated final rejection of God's love and their rebellion against His eternal law, that wonderful, loving, forgiving God will at last appear in His character as the enemy of that man or that nation.
