Scripture defines fearing God as hating evil (Pr 8:13), and exhorts all who love God to hate evil. (Ps 97:10) What is evil, and what does hating it feel like? How can we know if we hate evil, or measure how much we hate it? How can we grow in hating evil, and in loving and fearing God?
We should define evil (the way God does) as any tendency to want to sin, or to violate God’s law. (1Jn 3:4) Hating evil is detesting our tendency to want to break God’s law (Ro 7:24), any reluctance or hesitancy to obey God’s law with delight and joy, or any tendency to excuse or make light of any motive or attitude which deviates from perfect holiness. This is the way of the wicked, an abomination to Jehovah. (Pr 15:9)
We should be asking God to search our hearts, to try us and expose our thoughts to uncover our wicked ways (Ps 139:23-24a), any place where we’re not hating evil, where darkness still has a foothold (Pr 4:19), where the enemy can take us captive whenever he likes. (2Ti 2:26)
Our goal is to cooperate with God as He leads us in the everlasting way (Ps 139:24b), as He gives us repentance to acknowledge the truth (2Ti 2:25), the truth that sets us free. (Jn 8:32)
It is insufficient to merely stop desiring sin, to stop being tempted and drawn away by our lust (Ja 1:14), to be neutral or complacent about sin; sin must become utterly disgusting, repulsive, grotesque, abominable, dreadful.
We must begin to recognize what sin does to us and to God, what it costs God and us, and to identify it in all of its ugliness and horror. We cannot toy with sin safely. If we don’t hate sin, we don’t yet see it clearly: we need God to open our eyes and help our hearts understand. (Jn 12:40)
In hungering and thirsting after righteousness, God will fill us (Mt 5:6); in perfecting holiness (He 12:14) in the fear of God we will find it (Mt 7:7-8); in adding to our faith virtue, moral excellence, we build on the rock and find true freedom.
