Isaiah 48:11
For mine own sake, even for mine own sake, will I do it: for how should my name be polluted? and I will not give my glory unto another. For mine own sake, even for mine own sake, will I do it: for how should my name be polluted? and I will not give my glory unto another.
God acts for His own sake, even for His own sake, for the glory of His own name, and He will not let His name be polluted or dishonored nor give His glory to another. He does this not because of any merit in His people, not because of any goodness and devotion and purity He sees in those in high places, not because they have feared Him, and not because His church is righteous or obedient to His commandments. In verses 9-11 this means He restrains and defers His anger and judgment toward undeserving Judah, does not cut His people off, but bears long with backsliding Israel and refines and chooses them in affliction, and His preservation and refining of them uphold His name and glory.
This long forbearance extends to wayward leaders who have dishonored Him as false shepherds, who cherish covetousness, selfishness, self-exaltation and childish faults and remain deficient in love, grace and purity after years of experience. He spares them so the enemies of the truth will not triumph over them. Through Judah His name is to be exalted among the heathen, so that even people wholly unacquainted with His character and attributes may behold the glory of the divine character and have His merciful designs made plain. He makes His designs plain by continuing to send prophets who repeatedly call every one to turn from evil and from his evil way.
The chapter containing the verse represents the work of God's messengers in the present day, and ministers are urged to read it in that light. He carries forward His work of redemption in the hearts of His people. If His wayward people repent and turn from evil they can become witnesses to His truth and monuments of His power and grace.
