Let's look at the fully (together) --
43 “You have heard that it was said, ‘Love your neighbor and hate your enemy.’
44 But I tell you, love your enemies and pray for those who persecute you,
45 that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.
46 If you love those who love you, what reward will you get? Are not even the tax collectors doing that?
47And if you greet only your own people, what are you doing more than others? Do not even pagans do that?
48 Be perfect, therefore, as your heavenly Father is perfect."
See? The only perfect response to an enemy -- someone who has wronged us in some way -- is to love them.
No response is better. It is
the perfect response.
We are to do it Christ commands -- just as God loved us when we were enemies (ref :
6You see, at just the right time, when we were still powerless, Christ died for the ungodly. 7Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die. 8But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. --- For if, while we were God’s enemies, we were reconciled to him through the death of his Son ... "
See -- God did this for us even when we were enemies!
That's "perfect".
We are also to be perfect the same way -- to love those we come into conflict with, instead of striking them, or ignoring them, or brushing them off, etc.
'If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
4Love is patient, love is kind. It does not envy, it does not boast, it is not proud.
5It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
6Love does not delight in evil but rejoices with the truth.
7It always protects, always trusts, always hopes, always perseveres.
8Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away.
9For we know in part and we prophesy in part,
10but when completeness comes, what is in part disappears.'
We are not perfect in the full way, but we are to do the perfect action, just as our Father in Heaven has done, of loving our enemies.
He asks, no...commands us to do this, and it's something we can do if we are looking to Him, keeping our eyes on Him, remaining in Him, relying on Him, praying as He said, then we very much definitely can do as He said here. But prayer -- this is very helpful quite often!
