there actually is a command/ teaching that keps a repentant and obedient person "perfect" and likens Him to the Father...but you have to accept and obey it.
matthew 5:43-48 "
You have heard that it was said, ‘Love your neighbor and hate your enemy.’44But I tell you, love your enemies and pray for those who persecute you,45that 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.46If 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?48Be perfect, therefore, as your heavenly Father is perfect."
which the teaching isnt "be perfect" the teaching is to be like God, be merciful even to enemies, forgive, actually treat those who wrong you with mercy, with Loving actions. in obeying this He actually" likens us to be as the Father" God has been merciful to forgive our prior lives, we have all wronged one another, which is a transgression of the Law. therefore we have sinned against God. He has poured mercy out from The body of Jesus Christ upon even the worst, and as all of the gospel, we are to return the same Love He gave. His commands are about treating other people with Loving actions, and in Christ, this is what "perfects" repentance is a command, that is found also in repenting of inward evil like lust, greed pride ect because thats where the actions are born and come forth from.
Perfection is found in " forgiving others when they offend you, in Loving those who dont love us, Just as God has Loved us, who did not Love Him. There will be no sin in eternal Life, there will be nothing but sin in eternal torment, repentance is a wonderful thing, its a gift to submit to God and resist satan, never fails
