On the Making of Resolutions
I find, by experience, that, let me make resolutions, and do what I will, with never so many inventions, it is all nothing, and to no purpose at all, without the motions of the Spirit of God; for if the Spirit of God should be as much withdrawn from me always, as for the week past, nothwithstanding all I do, I should not grow, but should languish, and miserably fade away. I perceive, if God should withdraw his Spirit a little more, I should not hesitate to break my resolutions, and should soon arrive at my old state. There is no dependence upon myself. Our resolutions may be at the highest one day, and yet, the next day, we may be in a miserable dead condition, not at all like the same person who resolved. So that it is to no purpose to resolve, except we depend on the grace of God.
