well you and me have a very different idea of what perfect looks like then
I do believe perfect is sinless. perfect is the glorified bodies we get that don't grow old or become sick or sin that is according to scripture also
I do believe we are made a millions times better once being born again now in the flesh and our hearts are changed, so I think we see things pretty similar, we may just look at the word perfect differently
Perfect is having our heart always toward God even when we occasionally may look away from Him. God does not overlook our looking away, but he is looking to improve us. He knows that we cannot do it ourselves. But if our heart is right then the improvement will be made because He is there. Consider the situation with King David when he had sinned with Uriah and Bathsheba. When he was caught and confronted by the prophet Nathan, David was then ready to take what the law of Moses required, death for murder and death for adultery:
"And David said unto Nathan, I have sinned against the LORD. And Nathan said unto David, The LORD also hath put away thy sin; thou shalt not die." II Sam 12:13
This was the difference between David and his predecessor, King Saul. Saul had also sinned against God, but Saul tried to justify himself and to blame the people when he failed to kill all of the Amalekites.
David had the perfect heart for the situation. Saul did not.
Consider also Job as we see him here:
"There was a man in the land of Uz, whose name was Job;
and that man was perfect and upright, and one that feared God, and eschewed evil." Job 1:1
How perfect was Job? For what he had and what he did with what he had he was perfect in the eyes of God. From that verse the Book of Job goes on and the hedge around Job is removed and he goes through hell. God wanted Job to grow and Job did. Was he perfect at the end of the Book? The word, perfect, is not used again but during and after being rebuked, Job says:
"Behold, I am vile; what shall I answer thee? I will lay mine hand upon my mouth.
Once have I spoken; but I will not answer: yea, twice; but I will proceed no further." Job 40:4-5
"I have heard of thee by the hearing of the ear: but now mine eye seeth thee.
Wherefore I abhor myself, and repent in dust and ashes." Job 42:5-6
And then God blesses Job again. In his heart, a perfect heart at the end Job had pleased God.
Perfection in the eyes of God is doing really the best we can with what we have. God recognizes our frailty and allows us improve and helps us to improve if our heart is pointed in that direction:
"But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more." Luke 12:48
In the end perfect will also be sinless, but we may have some growing to do to get there. Will not God help us is we ask Him or sometimes even if we do not? Does God not love us even more than we have loved our own natural children?
"Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:
For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
Or what man is there of you, whom if his son ask bread, will he give him a stone?
Or if he ask a fish, will he give him a serpent?
If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?" Matt 7:7-11
