I am reminded of the rich young ruler who was about as perfect as any man can get. Jesus said that in order to be completely perfect he had to sell all he had, give it to the poor, and follow Him- kind of like a vagabond. Then Jesus said, "With man this is impossible, but with God all things are possible."
So, the fact that he couldn't give up his riches for the sake of Christ, wouldn't that be idolatry? We could say the young man's understanding of the 10 commandments was a bit shallow. We can't not sin... unless God saves us and empowers us with His Spirit.
Does not our sin nature hold us in bondage, and cause us to sin, until we place our faith in Christ?
If Jesus wasn't born with a sin nature, (which I believe he wasn't) then could he have sinned if he wanted to? I would say no because, being God, He is the standard of what is holy and what is sinful
