Yelsew,
If even one man is "upright", "Perfect", then TOTAL DEPRAVITY CANNOT EXIST! Calvinism refuted by a Calvinist! Amazing!
Job was upright, not perfect. Similarly, Abraham was upright but not perfect. The Bible says that Abraham's faith was counted as righteousness. Perhaps it was the same with Job. He certainly was not, nor ever implied to be, sinless.
But wait a minute, is it not also a Calvinist tenet that Jesus was fully human? If fully human, then you must acknowledge that a human lived a perfect sinless life of his own free will. Wasn't he tempted in all that was common to man? This situation also completely refutes Total Depravity. Depravity cannot be total if it exempts even one human!
Yes, Jesus was fully human. Yes, He had a human nature. However, He also had a perfectly Divine nature too. He was two natures in one person. Now what does all that mean?!
First of all, many (as you have implied here) beleive that sin is essential to humanity. It is not. The sinful conditon came onto humans AFTER the creation. We were intended to be without sin. We were not created sinful.
Christ is a special creation (Thus the "Second Adam" idea). Jesus' sinlessness should not call into question His humanity. His sinlessness actually defines what humanity was intended to be from the beginning. Jesus is the pattern for what humanity should be. He is the standard, not us.
There are some givens and theological thoughts that must go into this idea:
1. Jesus never sinned.
2. Jesus was tempted by Satan with real temptations.
Facts are important. However there is a third and most important fact.
3. James 1:13 clearly states that God cannot be tempted with evil.
If, and this is a big if, Jesus' humanity was the only component to Himself, then yes, He could have sinned or had a sin nature like ours. However, Jesus' humanity is
Always united to His divinity. Therfore, since He is God and God cannot be tempted by evil, Jesus could not sin.
This situation also completely refutes Total Depravity. Depravity cannot be total if it exempts even one human!
Jesus was a completly different case. You are trying to compare apples to space shuttles here.
Blessings,
Archangel
