But although our mind cannot conceive of God, without rendering some worship to him, it will not, however, be sufficient simply to hold that he is the only being whom all ought to worship and adore, unless we are also persuaded that he is the fountain of all goodness, and that we must seek everything in him, and in none but him. My meaning is: we must be persuaded not only that as he once formed the world, so he sustains it by his boundless power, governs it by his wisdom, preserves it by his goodness, in particular, rules the human race with justice and Judgment, bears with them in mercy, shields them by his protection; but also that not a particle of light, or wisdom, or justice, or power, or rectitude, or genuine truth, will anywhere be found, which does not flow from him, and of which he is not the cause; in this way we must learn to expect and ask all things from him, and thankfully ascribe to him whatever we receive. For this sense of the divine perfections is the proper master to teach us piety, out of which religion springs. By piety I mean that union of reverence and love to God which the knowledge of his benefits inspires. For, until men feel that they owe everything to God, that they are cherished by his paternal care, and that he is the author of all their blessings, so that nought is to be looked for away from him, they will never submit to him in voluntary obedience; nay, unless they place their entire happiness in him, they will never yield up their whole selves to him in truth and sincerity.
