Our greatness and wretchedness are so evident that the true religion must necessarily teach us that there is in us some great principle of greatness and some great principle of wretchedness. It must also account for such amazing contradictions. To make us happy it must show us that a God exists whom we are bound to love; that our only true bliss is to be in him, and our sole ill to be cut off from him. It must acknowledge that we are full of darkness which prevents us from knowing him, and so, with our duty obliging us to love God and our sin leading us astray, we are fully unrighteous. It must account to us for the way in which we thus go against God and our own good. It must teach us the cure for our helplessness and the means for obtaining the cure.
