"For our salvation it was
necessary that Jesus be free from sin. He was 'a lamb without blemish or spot,' able to offer His 'precious' blood for us (1 Pet. 1:19). If He had been sinful
He would have needed a savior Himself, and His death would not have helped us.
Christ obeyed on our behalf the moral commandments applying to all humanity. He
also fulfilled all the will of God applying to Him in particular, as the One
called to be the Messiah. His perfect obedience qualifies Him to be our
all-sufficient Savior." -R.C. Sproul
