God works in his elect in two ways: inwardly, by his Spirit; outwardly, by his Word.

For as the aged, or those whose sight is defective, when any book, however fair, is set before them, though they perceive that there is something written, are scarcely able to make out two consecutive words, but, when aided by glasses, begin to read distinctly, so Scripture, gathering together the impressions of Deity, which, till then, lay confused in our minds, dissipates the darkness, and shows us the true God clearly.

Doubtful prayer is no prayer at all.

The only skills I have the patience to learn are those that have no real application in life.

Scripture will ultimately suffice for a saving knowledge of God only when its certainty is founded upon the inward persuasion of the Holy Spirit. Indeed, these human testimonies which exist to confirm it will not be vain if, as secondary aids to our feebleness, they follow that chief and highest testimony. But those who wish to prove to unbelievers that Scripture is the Word of God are acting foolishly, for only by faith can this be known.

Who will venture to place the authority of Copernicus above that of the Holy Spirit?

We unjustly defraud God of his right, unless each of us lives and dies in dependence on His sovereign pleasure.
