If people have wronged you, they first must come to ask forgiveness. Anger sometimes expresses itself in name-calling and murder. 4 Most anger strains or breaks relationships. The Sermon on the Mount is about the love of God that calls sinners to repentance. It calls for an inner love that will show itself in outward actions.
Love demands honesty.
Deception has no place in love. Love is based on trust, and trust is broken by deception. This love is designed to reach not only friends, but also enemies. These enemies do not deserve love, but because of the love of God, they shall get it anyway. God, through you and your love, changes enemies into friends.
