Charles H. Spurgeon on Psalms 79:9

"For thy name's sake." The good which God doth unto his church, be it temporal or spiritual, is for his own sake. What I do (saith God), I do for mine holy name's sake; there is nothing to move me but mine own name; that is holy, great, and glorious, and I will for my name's sake do much for my church and people. That they were preserved in Babylon, was for his holy name's sake; that they were brought out of Babylon, was for his holy name's sake; that they were replanted in Canaan, was for his holy name's sake; that they had a temple, sacrifices, priests, prophets, ordinances again, was for his name's sake; when they were near to destruction often, in former days, God wrought for his name's sake, Ezek. 20; so Isaiah 48:8, 9. It is not for the enemies' sake that God doth preserve or deliver his people; nor for their sakes, their prayers, tears, faith, obedience, holiness, that he doth great things for them, bestows great mercies upon them; but it is for his own name's sake. For man's sake God cursed the earth, Gen. 8:21; but it is for his name's sake that he blesseth it. The choicest mercies God's people have, are for his name's sake; they have pardon of sin for his name's sake, Ps. 25:11, 1 John 2:12; purging of sin for his name's sake; Ps. 79:9; leading in the paths of righteousness for his name's sake, Ps. 23:2; quickening of their dead and dull hearts for his name's sake, Ps. 143:11. Though his people offend him, yet he forsakes them not, for his great name's sake.—William Greenhill.
