For He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him. – 2 Corinthians 5:21

There never was in the heart of our blessed Lord a wish for an evil pleasure, nor a desire to escape any suffering or shame which was involved in His service. When He said, “Father, if it be possible, let this cup pass from Me,” He never desired to escape the bitter potion at the expense of His perfect lifework. The “if it be possible,” meant, “if it is consistent with full obedience to the Father, and the accomplishment of the divine purpose.” We see the weakness of His nature shrinking, and the holiness of His nature resolving and conquering, as He adds, “nevertheless, not as I will, but as You will.” He took upon Him the likeness of sinful flesh, but though that flesh often caused Him weariness of body, it never produced in Him the weakness of sin. He took our infirmities, but He never exhibited an infirmity which had the least of blameworthiness attached to it. Never fell there an evil glance from those blessed eyes; never did His lips let drop a hasty word; never did those feet go on an ill errand, nor those hands move towards a sinful deed; because His heart was filled with holiness and love. Within as well as without our Lord was unblemished. His desires were as perfect as His actions. Searched by the eyes of Omniscience, no shadow of fault could be found in Him.

Yes, more, there were no tendencies about our Substitute towards evil in any form. In us there are always those tendencies; for the taint of original sin is upon us. We have to govern ourselves and hold ourselves under stern restraint, or we should rush headlong to destruction. Our carnal nature lusteth to evil, and needs to be held in as with bit and bridle. Happy is that man who can master himself. But with regard to our Lord, it was His nature to be pure, and right, and loving. ~ C.H. Spurgeon
