God summons us to a radical imitation of God. To become like God, we should imitate God. When Jesus says Be perfect as your heavenly Father is perfect, I think this is what he means. He goes on to say your love must know no bounds, as your heavenly Father’s love knows no bounds. We are being reminded that if we abandon our egoistical identification with our own individuality, if we let go of ourselves, we plunge into kenosis, into self-emptying, into our true self. We will be made into the original being we are. We will become original, because we will be united with our origin, we will discover our unique relationship through union with the origin of all things.
