Matthew 5:43-48 Love Your Enemies.
Jesus was a theonomist, because he continually quoted not just from the ten commandments, but from the law-code as well. In this case, “You shall love your neighbour,” is taken from Leviticus 19:18 and Deuteronomy 23:3-6 (v. 43). However, to “hate your enemy” is not found there (v. 43b). This was manmade tradition, which Jesus was repudiating. His message was diametrically opposed to this tradition. In loving our enemies we are to in fact bless those who curse us, do good to those who hate us, and pray for those who spitefully use and persecute us (v. 44 Cf. Lk. 6:27). This is called radical discipleship, but the way for all the followers of Jesus in our personal conduct, even with enemies. Our pattern, besides Jesus, is in fact the Father who “makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust” (v. 45). We might call this his “common grace,” which he shows to all his creatures as their Creator. It is the same grace we are to show to our neighbours near and far (vv. 46-47 Cf. Lk. 6:32; Eph. 5:1). This is true perfection (v. 48 Cf. Col. 1:28; 4:12).
