The Cause

In order to apprehend God, Calvin suggests we need to believe that He ought to be honoured, but also that he is the fountain of every good. Calvin writes,

... 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 ...
