Question: Is the fear of the Lord to hate all evil or not?
If it is, then there is obviously a time to hate.
Question: Is anger a sin?
If it is, then you condemn the Sinless One as a liar, for He was angered by moneychangers in the Temple.
Ephesians 4:26-31
26 “In your anger do not sin” : Do not let the sun go down while you are still angry, 27 and do not give the devil a foothold. 28 Anyone who has been stealing must steal no longer, but must work, doing something useful with their own hands, that they may have something to share with those in need. 29 Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. 30 And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. 31 Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice.
James 1:19-20
19 My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, 20 because human anger does not produce the righteousness that God desires.
Proverbs 29:11
11 Fools give full vent to their rage, but the wise bring calm in the end.
