Those who have received salvation are to attribute it to sovereign grace alone, and to give all the praise to Him, who makes them to differ from others. —Jonathan Edwards
The doctrines of grace are so called because these five major headings of theology, often identified as the five points of biblical Calvinism, contain the purest expression of the saving grace of God. Each of these five doctrines—radical depravity, sovereign election, definite atonement, irresistible call, and preserving grace—supremely display the sovereign grace of God. These five headings stand together as one comprehensive statement of the saving purposes of God. For this reason, there is really only one point to the doctrines of grace, namely, that God saves sinners by His grace and for His glory. These two realities—God’s grace and glory—are inseparably bound together. Whatever most magnifies God’s grace most magnifies His glory. And that which most exalts God’s grace is the truth expressed in the doctrines of grace.
On the other hand, compromising any one of the five points dilutes and diminishes the grace of God. For instance, to speak of a mere partial corruption of man, one in which the lost sinner is only spiritually sick in his sin, makes a misdiagnosis that grossly diminishes the grace of God. Likewise, to espouse a conditional election that is dependent upon God’s foresight of man’s faith corrupts the grace of God. To teach that Christ made a universal atonement, making salvation possible for all (though actual for none), cheapens the grace of God. To believe in a resistible call that allows for the free will of man compromises the grace of God. And to think of reversible grace, which would allow man to fall away from the faith, contaminates the pure grace of God. These views undermine the grace of God, and because of that, sad to say, they rob God of His glory. And yet, such views are widely held in the church today. In any syncretistic Arminian scheme of theology, salvation is seen as being partly of God and partly of man—whether it be that man adds his good works or that he contributes his own self-generated faith to the finished work of Christ. These schemes divide the glory between God and man. To whatever extent one deviates from any of the five doctrines of grace, one marginalizes the glory that is due to God alone for the salvation of sinners.
Giving Glory to God Alone
Writing shortly before his death in 2000, James Montgomery Boice noted:
Having a high view of God means something more than giving glory to God . . . it means giving glory to God alone. This is the difference between Calvinism and Arminianism. While the former declares that God alone saves sinners, the latter gives the impression that God enables sinners to have some part in saving themselves. Calvinism presents salvation as the work of the triune God—election by the Father, redemption in the Son, calling by the Spirit. Furthermore, each of these saving acts is directed toward the elect, thereby infallibly securing their salvation. By contrast, Arminianism views salvation as something that God makes possible but that man makes actual. This is because the saving acts of God are directed toward different persons: the Son’s redemption is for humanity in general; the Spirit’s calling is only for those who hear the gospel; narrower still, the Father’s election is only for those who believe the gospel. Yet in none of these cases (redemption, calling, or election) does God actually secure the salvation of even one sinner! The inevitable result is that rather than depending exclusively on divine grace, salvation depends partly on a human response. So although Arminianism is willing to give God the glory, when it comes to salvation, it is unwilling to give Him all the glory. It divides the glory between heaven and earth, for if what ultimately makes the difference between being saved and being lost is man’s ability to choose God, then to just that extent God is robbed of His glory. Yet God Himself has said, “I will not yield My glory to another” (Isa. 48:11).
This is why the doctrines of grace are so desperately needed in our churches. They give glory to God alone. They define salvation as being all of God. When salvation is correctly perceived in this way, then—and only then—God receives all the glory for it. Only sola gratia produces soli Deo gloria.
