Romans 12:9 says to "Abhor what is evil" and "cleave to what is good".
To Abhor something.. is to HATE it.
So the Bible says to hate what is evil.. and cling to what is good.
All sin is evil, so we should Abhor it.. hate it.
But OBEDIENCE (to God's commands) is good... So we should strive to cling to it.
God hates all sin, because sin is a transgression of God's law.
(1 John 3:4)
Sin is "rebellion" against the will of God.
What parent likes being rebelled against by their children when they instruct a child to do something? Parents want to be honored by their children through obedience and faithfulness.
God is no different.
So the more a child of God grows in the knowledge of Christ, the more our love grows for God.
The things that we know break God's heart, will break ours as well.
The closer you draw to him...
The more you will love what he loves, and hate what he hates.
