I'm reminded of this passage:
But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you, - Matthew 5:44 http://www.biblegateway.com/passage/?search=Matthew5:44&version=NKJV
Which leads to this:
If your enemy is hungry, give him bread to eat; And if he is thirsty, give him water to drink;For so you will heap coals of fire on his head, And the Lord will reward you. - Proverbs 25:21-22 http://www.biblegateway.com/passage/?search=Proverbs25:21-22&version=NKJV
And I'm reminded of what the law cannot do.
Romans 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
Galatians 2:21 I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
In other words, you can't command someone to love.
