But I say to you, love your enemies and pray for those who persecute you so that you may be children of your Father in heaven. - Matthew 5:44
This is a twist on the Golden Rule that we don’t like too much. What is more worrisome is the condition that Jesus has attached. If we are hearing Him aright, He is telling us that we have to practice this if we would claim the right to pray “Our Father...”
We must ask for the grace to pray seriously for those in our enemy categories: a family member, an acquaintance, an international terrorist... This is personal and very real.
