We are not merely passive nor yet does God do some, and we do the rest. But God does all, and we do all. God produces all, and we act all. For that is what he produces, viz. our own acts. God is the only proper author and fountain; we only are the proper actors. We are, in different respects, wholly passive and wholly active.
In the Scriptures the same things are represented as from God and from us. God is said to convert (2 Tim. 2:25), and men are said to convert and turn (Acts 2:38). God makes a new heart (Ezek. 36:26) and we are commanded to make us a new heart (Ezek. 18:31). God circumcises the heart (Deut. 30:6), and we are commanded to circumcise our own hearts (Deut. 10:16); not merely because we must use the means in order to the effect, but the effect itself is our act and our duty. These things are agreeable to that text, “God worketh in you both to will and to do” (Phil. 2:13).
