In Matthew 5:44, Jesus said, "Love your enemies and pray for those who persecute you." That has always been a tough verse for me. It just isn't natural to pray for those who lie, cheat, steal, murder and seek to do harm to the Body of Christ. But Christ himself commanded us to do just that.
Therefore, I believe we can and should love our enemies. That is why we should pray continually for our leaders in Washington.
