He that spared not his own Son

He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Romans 8:32 

God gave us the gift of his Son.  The phrase “spared not” is a reference to Christ’s death as a punishment for sin, not his sin, but our sin. Why?  Romans 1-8 tells us why. 

But the question might arise: maybe God has only done so much and rest is up to me?  Paul’s answer is that if God has given us his Son, he will surely give everything necessary for our salvation.  It is an argument from the greater to the lesser – there is nothing greater than the gift of God’s Son.  Having that, we have no reason to think that God will withhold any other blessing. 

It is this argument that Toplady so eloquently expresses in this hymn:

From whence this fear and unbelief? Hath not the Father put to grief His spotless Son for me? And will the righteous Judge of men Condemn me for that debt of sin Which, Lord, was charged on Thee?

Complete atonement Thou hast made, And to the utmost Thou hast paid Whate’er Thy people owed; How then can wrath on me take place, If sheltered in Thy righteousness, And sprinkled with Thy blood?

If thou hast my discharge procured, And freely in my room endured The whole of wrath divine; Payment God cannot twice demand, First at my bleeding Surety’s hand, And then again at mine.

Turn then, my soul, unto thy rest! The merits of thy great High Priest Have bought thy liberty; Trust in His efficacious blood, Nor fear thy banishment from God, Since Jesus died for thee.
