John Murray again;
The hallmark of Calvinism is unconditional election and that is exactly what this highest type of Arminianism vigorously denies. It professes indeed fixed and unchangeable election of individuals. But what is meant is, that, since God decrees to save all who believe and since He knows perfectly beforehand and from eternity who will believe, He on the basis of that foresight as ground and cause elects these individuals to eternal life. God elects all whom He foresees will believe and persevere to the end. His election then is determined by His foresight of some difference that comes to exist among men, a difference which He Himself does not cause but which in the final analysis is due to sovereign choice on the part of the human will. The determining factor in this type of election then is not the sovereign unconditioned good pleasure of God but the decision of the human will which God from eternity foresees. Election is not the source of faith, but faith foreseen is made the source or condition of election.On close examination it should be evident that this is not divine election at all. The sovereign determination of God is ruled out at the vital point, for the ultimate determinant of the discrimination that exists among men is made to be something in men and not the sovereign good pleasure of God. Indeed this type of Arminianism that at first appears to approach so closely to the Reformed position only serves to show more clearly the total difference between the two systems. The election taught in the Reformed Church is election to salvation and eternal life and therefore also to faith and all other graces as the means ordained of God to the accomplishment of His sovereign decree. Election is not then conditioned upon faith, but faith is the fruit of election. God sovereignly works faith in men because He has in His eternal counsel appointed them to salvation. Faith is not the logical prius of election, but election is the eternal prius and source of faith. Arminianism at its best denies all of these propositions.
The denial of unconditional election strikes at the heart of the doctrine of the grace of God. The grace of God is absolutely sovereign and every failure to recognize and appreciate the absolute sovereignty of God in His saving grace is an expression of the pride of the human heart. It rests upon the demand that God can deal differently with men in the matter of salvation only because they have made themselves to differ. In its ultimate elements it means that the determining factor in salvation is what man himself does, and that is just tantamount to saying that it is not God who determines the salvation of men, but men determine their own salvation; it is not God who saves but man saves himself. This is precisely the issue.
