While a distinction between sinner and sin is a handy one for protecting the individual from God’s hatred, it simply cannot bear up under the weight of Scriptural evidence which has God showing hatred, or wrath, resting on individuals. Jesus condemns people as workers of iniquity (Lk 13:27), and will take personal vengeance on those who reject God (2 Thes 1:8).
God’s hatred is a necessary part of His love. Whatever opposes, harms, defiles or otherwise threatens what He loves experiences His displeasure, often erupting in righteous indignation: a divine demand for change. We could say that God’s hatred is an ally of His love, destroying those things which are destructive of the true, the good and the beautiful. People who love what God loves are told to hate what He hates, or those who hate Him (Prv 8:13; Ps 139:21-22).
God hates several things: pride, lying, murder, evil thoughts, evil inclinations, bearing false witness, sowing discord among brethren (Prov 6:16-19), formalistic worship masking wicked living (Is 1:14), idolatry (Dt 16:22), and divorce (Mal 2:16), amongst other things. In fact, most every reference to something or someone being “an abomination to the Lord” refers to something that is loathsome or detestable to Him, a strong indicator of His hatred.
But the thorny question is this: does God hate individuals? Could a God of love hate people?
A plain reading of Scripture seems to indicate that, at least in some ways, He does. God is said to hate all workers of iniquity (Ps 5:5), and everyone who is wicked and loves violence (Ps 11:5). God told Israel that He hated the nations He was casting out before them (Lev 20:23). God said to Hosea that He hated Ephraim (Hos 9:15). He loved Jacob and hated Esau (Mal 1:3-4). Even where the word for hatred suggests something weaker than antipathy, one can hardly doubt that God directs this affection towards individuals and groups of people, not merely actions.
