To "hate your enemy" was never a law given by Moses to the people. This was a man's take on it. God loves all, even those who come against Him. Even those He knows will make the choice of hell over an eternity with Him. We can do no less on our part. We hate the sin, but love the sinner. Never cease in being Christ-like and praying for and giving to, others. God is no respector of persons and we should not be either.
Therefore "If your enemy is hungry, feed him; If he is thirsty, give him a drink; For in so doing you will reap coals of fire on his head." 21Do not be overcome by evil, but overcome evil with good. Romans 12:20-21
An example of selfless love can be found in the story of Stephen. I will refer to only a couple of passages which point to the kind of people we are called to be: And they stoned Stephen as he was calling on God and saying, "Lord Jesus, receive my spirit." 60Then he knelt down and cried out with a loud voice, "Lord, do not charge them with this sin." And when he had said this, he fell asleep. Acts 7:59-60
Stephen interceded for the very ones who killed him. This showed the same Christ-like love that Jesus showed His killers.
46For if you love those who love you, what reward have you? Do not even the tax collectors do the same? 47And if you greet your brethren only, what do you do more than others? Do not even the tax collectors do so? 48Therefore you shall be perfect, just as your father in heaven is perfect."
Let's cross-reference this passage containing the word perfect with the word blameless in Deuteronomy 18:13 since they can be similar in meaning. "You shall be blameless before the LORD your God." The word "blameless" in this passage points to integrity and dependence on God alone; not on false idols, self, or others.
There are several references to the word perfect (referring to the Christian) throughout the New Testament. The "perfect" Christian is a spiritually mature Christian. One that sacrifices self. One that has perservered through trials and learned to express God's genuine love to others. We are made complete in Christ by loving others, and the Father's love is perfected in us. We are set apart from the world. We love those whom the world deems unloveable by feeling and expressing selfless love as Christ did.
