9 Love must be sincere. Hate what is evil; cling to what is good.10 Be devoted to one another in love. Honor one another above yourselves.11 Never be lacking in zeal, but keep your spiritual fervor, serving the Lord.
I am a firm believer that love and hate are both capable of being infinite except for when they oppose each other. The more hate a person harbors for others, the less capacity for love he has. But the opposite is also true; the more love a person shows to others the less hate they harbor.
We are commanded to hate 'what' is evil, not 'who.' We are to hate their sins, but to show the person himself love. If we hate the people we are supposed to help, we are only going through the motions, but that help will likely not be received as being in love. Besides, God knows your heart.
1 John 2:9-10
9 Anyone who claims to be in the light but hates a brother or sister is still in the darkness.10 Anyone who loves their brother and sister lives in the light, and there is nothing in them to make them stumble.
