"You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you: Love your enemies and pray for those who persecute you" (Matthew 5:43-44, NIV).
Perhaps no one on earth hates Christians more than do the Islamic terrorists. Believing that they are following the will of God, they are intent on killing those who disagree with them. Without a doubt, followers of Jesus Christ are their enemies. We disagree with them at every point.
Our obligation is to pray for them. They need the grace and mercy of God. They are heading toward hell without any hope of escape, unless they come to know Christ as their Savior and Lord. We have been instructed to pray for them. Jesus wants to save them, and He wants us to cooperate with Him in His mission of salvation.
At http://www.atfp.org, we can adopt a terrorist for prayer. This is an excellent opportunity to love our enemies.
