Hate is a complex issue from a Christian viewpoint. The Bible speaks of both positive and negative aspects of hatred. It is acceptable to hate those things that God hates, which is proof of a right standing with God. For example, Psalm 97:10 says, "... Let those who love the Lord hate evil".
However, the hatred that is negative is that which is directed against others. Jesus mentions hatred in the Sermon on the Mount, saying that anyone who is angry with his brother will be subject to judgment.
