On the contrary, when we seek to know only what God would have us know, which is always done when our minds perfectly harmonize with the intimations of Providence, then the object of knowledge becomes one and the same to him who imparts knowledge and to him who receives it; and God and man are in union.
And this view, it may be properly added, is the more interesting and the more practically important, because it so fully recognizes God as the judge of what is proper or not proper to be known. Sovereign here as in other things, he not only retains the right and the power of communicating knowledge, but of communicating what, in his own judgment, he sees to be best. It is obviously not possible for him to communicate all knowledge to a limited mind, that can receive it only in parts. Adjusting, therefore. what he imparts not only to the capacity of the recipient but to the attendant circumstances, he gives here a little and there a little: casting brightness around the skirts of the clouds which overhang us, mingling light with darkness and darkness with light, so that those who walk in some things in the day of open vision, may still be said in other things to walk in "the night of faith."
