If we look carefully within ourselves, we shall find that there are certain limits beyond which we refuse to go in offering ourselves to God. We hover around these reservations, making believe not to see them, for fear of self-reproach. The more we shrink from giving up any such reserved point, the more certain it is that it needs to be given up. If we were not fast bound by it, we should not make so many efforts to persuade ourselves that we are free.
