You see, it was God's battle to fight.
Why do you suppose the enemy, Satan, loves to attack the children of God?
He certainly cannot attack God directly - he has no power against God and he knows that he is subject to God's sovereignty. And he knows his most effective weapon is to strike at the very heart of God through attacks on his children.
Of course, he has no power over God's children either, except what we willingly hand over to him.
When we mistakenly believe a battle is between us and Satan, or more often, between us and another person, we hand Satan a victory on a silver platter. We end up like two toddlers wrestling in the sand box over who will drive us home. We both belong to the same Father.
Satan is just a stranger seeking to kidnap us from our loving home and instead of standing united with our Father, we waste our time fighting one another. Regardless of what the offense or injury is, the battle is between God and Satan. We are the children of God and our Father wants to fight our battles for us! He is perfectly capable of crushing Satan's head. But we have to get out of the way and let Him take care of it.
How do we let God handle it? Isn't there SOMETHING we need to do?
Jesus gave us the play book for winning every battle. Our instructions are simple and go something like this, "You have heard it was said, 'Love your neighbor and hate your enemy.' But I tell you: Love your enemies and pray for those who persecute you that you may be sons of your Father in heaven." (Matthew 5:44-45) Whatever the disagreement, victimization, abuse, torture, cruelty, offense, or insult, the instructions to us are the same. "Pray for the person who hurt you."
Not in the Valentine's Day, send-them-a-box-of-candy-and-a-Hallmark-card kind of way. And not by simply saying words without meaning. Love is an action demonstrated most perfectly in Christ's sacrificial death on the cross.
Loving them means giving yourself up for them. Giving until you cannot give any more and then praying that God will give you more so you can give that away too.
Luke 6:27-30 takes this radical love thing even farther, "But I tell you who hear me: Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you. If someone strikes you on one cheek, turn to him the other also. If someone takes your cloak, do not stop him from taking your tunic." And in verse 35, "But love your enemies, do good to them and lend to them without expecting to get anything back. Then your reward will be great, and you will be sons of the Most High because he is kind to the ungrateful and wicked."
Are you one who hears Him? Remember, it is not a battle between two people. It is God's battle. "The Lord will fight for you; you need only to be still."
