Christian practice is a distinguishing and sure evidence of grace to persons' own consciences. We cannot reasonably suppose, when the Scripture in this case speaks of good works, good fruit, and keeping Christ's commandments, that it has respect merely to what is external, or the motion and action of the body, without including respect to any aim or intention of the agent, or any act of his understanding or will. For consider men's actions so, and they are no more good works or acts of obedience, than the regular motions of a clock; nor are they considered as any human actions at all.
