Strive for perfection in love.
Jesus expands on the law that his followers knew well. As God loves all people without partiality the bad and the good, the just and the unjust so are all who follow him to do. Certainly this can be difficult, but it is not impossible. For by Christ's sacrifice, we have been made children of the Father. With his help, and God's grace, we are capable of striving for the perfection in love to which we are called.
