I appreciate the question because for me... I used to try to be like Christ before I understood that He was God, and before I understood the gospel message. The reason I am bringing up my experience is because I actually understood Christ to be the Son of God not because of His divinity, but because of how He lived. In other words that He wasn't any more special than I could be.
I found myself trying to live up to the standard of Christ, and I failed miserably. My attempts to live like Christ had no power, meaning I had no strength in me on a day to day basis to live up to the standard. I was tired of failing and always felt guilty because of my weakness to sin.
So then the question was how/where do I get the strength to do the things that God requires of me. That's when the Gospel became clear. Because I needed someone to do it for me, which couldn't be another sinful man like myself, but it had to be a sinless man, and what man is sinless? Only God could be sinless, so therefore Jesus being the Son of God, could be the perfect Man, and could do what I couldn't. And once He did it for me, all I could do is believe on Him and His finished work. Then once I had faith in Him, I was now enabled to do the things I couldn't do before because I had Christ living within me.
So, actually what you desire to do, which is to emulate Christ, is possible because of His divinity.
Very truly I tell you, whoever believes in me will do the
works I have been doing, and they will do even greater things than
Paul explains here the impossibility of doing good in our own strength, and that the only one to deliver us from this is Christ:
For I do not do the good I want, but the evil I do not want is what I keep on doing.
24Wretched man that I am! > Who will deliver me from this body of death? 25Thanks be to God through Jesus Christ our Lord!
It is Christ living in you that enables you to live for Him. If Christ wasn't God He couldn't dwell in us, allow us to live for Him.
I have been crucified with Christ; it is no longer I who live, but Christ lives in me...
If we could live sinless lives by our own strength, then Christ would not have had to die for us.
I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain.
We are created in Christ (if anyone is in Christ, he is a new creation 1 Cor 5:17) for good works, but we must be in Christ.
8For by grace you have been saved through faith, and
that not of yourselves; it is the gift of God, 9not of works, lest
anyone should boast. 10For we are His workmanship, created in Christ
Jesus for good works, which God prepared beforehand that we should
walk in them.
