As the Lord says, He makes the sun to shine and the rain to fall on the unjust and the wicked as well as on the godly.  And His followers are required to act accordingly.  Christ commands us to love our enemies, and uses as His model the fact that God from heaven showers His blessings on the wicked.  We see that God actually hates and is infinitely angry with persons upon whom He pours great blessings.  We are not allowed to hate persons, but are commanded to love them.  We cannot, of course, be pleased with persons who hate God and hate us, but we can behave lovingly toward them and pray for them.  In so doing, we follow the model of God.
