Romans 9:16

So then it is not of him that willeth--hath the inward desire nor of him that runneth--maketh active effort (compare Co1 9:24, Co1 9:26; Phi 2:16; Phi 3:14). Both these are indispensable to salvation, yet salvation is owing to neither, but is purely "of God that showeth mercy." See on Phi 2:12-13, "Work out your own salvation with fear and trembling: for it is God which, out of His own good pleasure, worketh in you both to will and to do."

We have here the apostle's solemn profession of a great concern for the nation and people of the Jews - that he was heartily troubled that so many of them were enemies to the gospel, and out of the way of salvation. For this he had great heaviness and continual sorrow. Such a profession as this was requisite to take off the odium which otherwise he might have contracted by asserting and proving their rejection.

Nay, Paul was so far from desiring it that he most pathetically deprecates it. And lest this should be thought only a copy of his countenance, to flatter and please them, I. He asserts it with a solemn protestation (Rom 9:1): I say the truth in Christ, "I speak it as a Christian, one of God's people, children that will not lie, as one that knows not how to give flattering title." Or, "I appeal to Christ, who searches the heart, concerning it." He appeals likewise to his own conscience, which was instead of a thousand witnesses. That which he was going to assert was not only a great and weighty thing (such solemn protestations are not to be thrown away upon trifles), but it was likewi…
