Here is another good quote from J. Oswald Sanders book "The Incomparable Christ" in which Sanders demonstrates the perfect sinless life Jesus lived.
"The Incomparable Christ"
"A study of Jesus' life reveals a consistent sense of immunity from sin. Never did He evince the slightest discontent with Himself - a grave fault in any other man. Never did He shed a tear over conscious failure. He demanded penitence of others, yet was never penitent Himself. Nor can this self-satisfaction be explained on the grounds that His standard of duty or sense of moral obligation was less exacting than that of His contemporaries. The reverse was the case. His code of ethics was immeasurably higher than theirs, yet not once does He admit that He has in any degree fallen short of His own standards. At the end of His life, as He communed with His Father in His loving sacerdotal prayer, He claimed to have accomplished perfectly the work entrusted to Him (John 17:4). In any other case than His, we would be justified in regarding such claims as obnoxious pride and arrant hypocrisy. In His case, the facts substantiate the claim."
