Deuteronomy 32:27

Deuteronomy 32:27. That I feared the wrath of the enemy, lest their adversaries should behave themselves strangely, and lest they should say, Our hand is high, and the LORD hath not done all this.

So he spared them for his own name’s sake; and, to this day, when God can find no other reason for showing mercy to the guilty, he does it for his name’s sake; and this is a blessed plea, to be urged by a man who can see no reason why God should have mercy upon him. He may say, "Lord, do it for thy name’s sake, to make thy grace and thy mercy illustrious, in the salvation of such a poor, hopeless wretch as I am."
