The Characteristics of Perfection

Love your enemies; do good to those who hate you and pray for those who persecute  and slander you, for if you  love only those who love you,  what reward will you have? Do not the publicans do the same? If you greet only your brothers, what are you doing that is more than what others do? Do not the pagans also do the same? Therefore, be perfect as your heavenly Father is perfect. (Mt. 5:44, 46-48)
