“The pious heart therefore perceives a division in itself, being partly affected with delight through a knowledge of the divine goodness, partly distressed with sorrow through a sense of its own calamity; partly relying on the promise of the gospel, partly trembling at the evidence of its own iniquity; partly exulting in the knowledge of life, partly alarmed by the fear of death. This variation happens through the imperfection of faith; since we are never so happy during the present life as to be cured of all diffidence, and entirely filled and possessed by faith. Hence those conflicts, in which the diffidence which adheres to the relics of the flesh rises up in opposition to the faith formed in the heart. But if in the mind of the believer assurance be mixed with doubts, do we not always come to this point, that faith consists not in a certain and clear, but only in an obscure and perplexed knowledge of the divine will respecting us? Not at all. For if we are distracted by various thoughts, we are not therefore entirely divested of faith; neither, though harassed by the agitations of diffidence, are we therefore immerged in its abyss; nor if we be shaken, are we therefore overthrown. For the invariable issue of this contest is, that faith at length surmounts those difficulties from which, while it is encompassed with them, it appears to be in danger.”
