Remember the words of Scripture,
Scarcely for a righteous man will one die; peradventure, for a good, a generous man, one might even dare to die; but God commendeth his love towards us, in that while we were yet sinners, Christ died for the ungodly. -Romans 5:7-8
He gave Himself. We cannot purchase the love of God. This highest expression of divine love, the gift of His own Son, was, in the nature of things, unpurchaseable. What could we have offered that God should come into this world, and be found in fashion as a man, and should die? Why, the works of all the angels in heaven put together could not have deserved one pang from Christ. If for ever the angels had continued their ceaseless songs, and if all men had remained faithful, and could have heaped up their pile of merit to add to that of the angels, and if all the creatures that ever were, or ever shall be, could each bring in their golden hemp of merit-yet could they ever deserve His cross? Could they deserve that the Son of God should hang bleeding and dying there? Impossible! It must be a gift, for it was utterly unpurchaseable; though all worlds were coined and minted, yet could they not have purchased a tear from the Redeemer; they were not worth it. It must be grace; it cannot be merit; He gave Himself.
And the gift is so thoroughly a gift that no prep of any kind was brought to bear upon the Saviour. There was no necessity that He should die, except the necessity of His loving us. ~ C.H. Spurgeon
