Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus. Let those of us who are mature think this way, and if in anything you think otherwise, God will reveal that also to you.
Philippians 3: 12-15

What is the meaning of perfection in the Bible? | GotQuestions.org
We wont reach total perfection while in our corrupted bodies. We will need new uncorrupted bodies to reach perfection. And by reaching perfection I mean being like Jesus Christ.
In terms of being Jesus Christ. I dont think we will ever be Jesus Christ. We are His children (example: Children of God). The bible does not say we are God, but rather that we are God's children if we truly believe in Jesus Christ.
But like Paul states we are to fight while in this body. There is no excuse to live a lifestyle of sin. We have been given the Spirit of God that will enable us to fight off our carnal/wordly/sinful desires, as long as we walk in the Spirit and not the flesh.
For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want.
Galatians 5:17
The one we let dominate will determine our success in pleasing God. Nonetheless it is our choice...Question one may have...How can I live by the spirit so that I can put to death the deeds of the flesh so that i can win this battle on earth so that I can be more like Jesus???
Answer: Turn away from wordly things and things that will quench the Spirit of God. Soak yourself in the bible on a daily basis, pray daily. Feed the spirit inside of you instead of the flesh. Fight to prevent wordly/sinful seeds to be planted in your heart. Fight to have the word of God planted in your heart and keep it secure.
Overall....Can the moon ever be the Sun? Nah....Can man ever be Jesus Christ? Nah...But can man be the children of God?...Of course, yes.
