Unmixed Grace: Calvin

8. For by grace are ye saved. This is an inference from the former statements. Having treated of election and of effectual calling, he arrives at this general conclusion, that they had obtained salvation by faith alone. First, he asserts, that the salvation of the Ephesians was entirely the work, the gracious work of God. But then they had obtained this grace by faith. On one side, we must look at God; and, on the other, at man.

God declares, that he owes us nothing; so that salvation is not a reward or recompense, but unmixed grace. The next question is, in what way do men receive that salvation which is offered to them by the hand of God? The answer is, by faith; and hence he concludes that nothing connected with it is our own. If, on the part of God, it is grace alone, and if we bring nothing but faith, which strips us of all commendation, it follows that salvation does not come from us.

Ought we not then to be silent about free-will, and good intentions, and fancied preparations, and merits, and satisfactions? There is none of these which does not claim a share of praise in the salvation of men; so that the praise of grace would not, as Paul shews, remain undiminished. When, on the part of man, the act of receiving salvation is made to consist in faith alone, all other means, on which men are accustomed to rely, are discarded. Faith, then, brings a man empty to God, that he may be filled with the blessings of Christ. And so he adds, not of yourselves; that, claiming nothing for themselves, they may acknowledge God alone as the author of their salvation.
