“Now faith is the evidence of things not seen.” Heb. 11:1.

1. For many ages it has been allowed by sensible men, Nihil est in intellectu quod non fuit prius in sensu: That is, “There is nothing in the understanding which was not first perceived by some of the senses.” All the knowledge which we naturally have is originally derived from our senses. And therefore those who want any sense cannot have the least knowledge or idea of the objects of that sense; as they that never had sight have not the least knowledge or conception of light or colours. Some indeed have of late years endeavoured to prove that we have innate ideas, not derived from any of the senses, but coeval with the understanding. But this point has been now thoroughly discussed by men of the most eminent sense and learning. And it is agreed by all impartial persons that, although some things are so plain and obvious that we can very hardly avoid knowing them as soon as we come to the use of our understanding, yet the knowledge even of these is not innate, but derived from some of our senses.

2. But there is a great difference between our senses, considered as the avenues of our knowledge. Some of them have a very narrow sphere of action, some a more extensive one. By feeling we discern only those objects that touch some part of our body; and consequently this sense extends only to a small number of objects. Our senses of taste and smell (which some count species of feeling) extend to fewer still. But on the other hand our nobler sense of hearing has an exceeding wide sphere of action; especially in the case of loud sounds, as thunder, the roaring of the sea, or the discharge of cannon; the last of which sounds has been frequently heard at the distance of near an hundred miles. Yet the space to which the hearing itself extends is small, compared to that through which the sight extends. The sight takes in at one view, not only the most unbounded prospects on earth, but also the moon, and the other planets, the sun, yea, the fixed stars; though at such an immeasurable distance, that they appear no larger through our finest telescopes than they do to the naked eye.

3. But still none of our senses, no, not the sight itself, can reach beyond the bounds of this visible world. They supply us with such knowledge of the material world as answers all the purposes of life. But as this was the design for which they were given, beyond this they cannot go. They furnish us with no information at all concerning the invisible world.

4. But the wise and gracious Governor of the worlds, both visible and invisible, has prepared a remedy for this defect. He hath appointed faith to supply the defect of sense; to take us up where sense sets us down, and help us over the great gulf. Its office begins where that of sense ends. Sense is an evidence of things that are seen; of the visible, the material world, and the several parts of it. Faith, on the other hand, is the “evidence of things not seen;” of the invisible world; of all those invisible things which are revealed in the oracles of God. But indeed they reveal nothing, they are a mere dead letter, if they are “not mixed with faith in those that hear them.”

5. In particular, faith is an evidence to me of the existence of that unseen thing, my own soul. Without this I should be in utter uncertainty concerning it. I should be constrained to ask that melancholy question,

Hear’st thou submissive; but a lowly birth, Some separate particles of finer earth

But by faith I know it is an immortal spirit, made in the image of God; in his natural and his moral image; “an incorruptible picture of the God of glory.” By the same evidence I know that I am now fallen short of the glorious image of God; yea, that I, as well as all mankind, am “dead in trespasses and sins:” So utterly dead, that “in me dwelleth no good thing;” that I am inclined to all evil, and totally unable to quicken my own soul.

6. By faith I know that, besides the souls of men there are other orders of spirits; yea, I believe that

Millions of creatures walk the earth, Unseen, whether we wake, or if we sleep.

These I term angels, and I believe part of them are holy and happy, and the other part wicked and miserable. I believe the former of these, the good angels, are continually sent of God “to minister to the heirs of salvation;” who will be “equal to angels” by and by, although they are now a little inferior to them. I believe the latter, the evil angels, called in Scripture, devils, united under one head, (termed in Scripture, Satan; emphatically, the enemy, the adversary both of God and man,) either range the upper regions; whence they are called “princes of the power of the air;” or like him, walk about the earth as “roaring lions, seeking whom they may devour.”

7. But I know by faith that, above all these, is the Lord Jehovah, he that is, that was, and that is to come; that is God from everlasting, and world without end; He that filleth heaven and earth; He that is infinite in power, in wisdom, in justice, in mercy, and holiness; He that created all things, visible and invisible, by the breath of his mouth, and still “upholds” them all, preserves them in being, “by the word of his power;” and that governs all things that are in heaven above, in earth beneath, and under the earth. By faith I know “there are three that bear record in heaven, the Father, the Word, and the Holy Spirit,” and that “these Three are One;” that the Word, God the Son, “was made flesh,” lived, and died for our salvation, rose again, ascended into heaven, and now sitteth at the right hand of the Father. By faith I know that the Holy Spirit is the giver of all spiritual life; of righteousness, peace, and joy in the Holy Ghost; of holiness and happiness, by the restoration of that image of God wherein we are created. Of all these things, faith is the evidence, the sole evidence, to the children of men.
