Certainly it is true that Jesus is the only One who lived without committing a single act of disobedience. His reason for living that perfect, victorious life is laid out in Romans 8:3, 4:
For what the law could not do in that it was weak through the flesh, God did by sending his own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit.
Do not miss the point that Jesus came to condemn sin by His perfect life in the flesh in order that “the righteous requirement of the law” might be fulfilled in us.
What is that righteousness? The Greek word “dikaima” used here means, literally, “the just requirement” of the law.
This means that Christ won His perfect victory in order to make the same victory available to us."
