Unfair Grace?

"The overwhelming majority of professing Christians grants that God is sovereign over nature and that He is sovereign over human behavior. The affirmation of divine sovereignty starts to disappear, however, when Christians begin to struggle over the third area in which the Scriptures affirm God's sovereignty--His grace. Somehow the idea that God reserves to Himself eternally and absolutely the right to manifest His saving mercy on some individuals and to withhold it from others is an act we adjudge to be unfair. The apostle Paul anticipated this human reaction to divine sovereignty in salvation when he raised the rhetorical question, "Is there injustice on God's part?" (Rom. 9:14b). Such a question has never been raised about Arminian or semi-Pelagian schemes of salvation. The suggestion of unrighteousness in God comes only in response to the affirmation of the absolute sovereignty of God in His saving choice to elect some and not others."--R.C. Sproul
