For we walk - To walk, in the Scriptures often denotes to live, to act, to conduct in a certain way; see the notes on Romans 4:12; Romans 6:4. It has reference to the fact that life is a journey, or a pilgrimage, and that the Christian is traveling to another country. The sense here is, that we conduct ourselves in our course of life with reference to the things which are unseen, and not with reference to the things which are seen.

By faith - In the belief of those things which we do not see. We believe in the existence of objects which are invisible, and we are influenced by them. To walk by faith, is to live in the confident expectation of things that are to come; in the belief of the existence of unseen realities; and suffering them to influence us as if they were seen. The people of this world are influenced by the things that are seen. They live for wealth, honor, splendor, praise, for the objects which this world can furnish, and as if there were nothing which is unseen, or as if they ought not to be influenced by the things which are unseen. The Christian, on the contrary, has a firm conviction of the reality of the glories of heaven; of the fact that the Redeemer is there; of the fact that there is a crown of glory; and he lives, and acts as if that were all real, and as if he saw it all. The simple account of faith, and of living by faith is, that we live and act as if these things were true, and suffer them to make an impression on our mind according to their real nature; see the note on Mark 16:16.

It is contradistinguished from living simply under the influence of things that are seen. God is unseen - but the Christian lives, and thinks, and acts as if there were a God, and as if he saw him. Christ is unseen now by the bodily eye; but the Christian lives and acts as if he were seen, that is, as if his eye were known to be upon us, and as if he was now exalted to heaven and was the only Saviour. The Holy Spirit is unseen; but he lives, and acts as if there were such a Spirit, and as if his influences were needful to renew, and purify the soul. Heaven is unseen; but the Christian lives, and thinks, and acts as if there were a heaven, and as if he now saw its glories. He has confidence in these, and in kindred truths, and he acts as if they were real. Could man see all these; were they visible to the naked eye as they are to the eye of faith, no one would doubt the propriety of living and acting with reference to them.

But if they exist, there is no more impropriety in acting with reference to them than if they were seen. Our seeing or not seeing them does not alter their nature or importance, and the fact that they are not seen does not make it improper to act with reference to them. There are many ways of being convinced of the existence and reality of objects besides seeing them; and it may be as rational to be influenced by the reason, the judgment, or by strong confidence, as it is to be influenced by sight. Besides, all people are influenced by things which they have not seen. They hope for objects that are future. They aspire to happiness which they have not yet beheld. They strive for honor and wealth which are unseen, and which is in the distant future. They live, and act - influenced by strong faith and hope - as if these things were attainable; and they deny themselves, and labor, and cross oceans and deserts, and breathe in pestilential air to obtain those things which they have not seen, and which to them are in the distant future.

And why should not the Christian endure like labor, and be willing to suffer in like manner, to gain the unseen crown which is incorruptible, and to acquire the unseen wealth which the moth does not corrupt? And further still, the people of this world strive for those objects which they have not beheld, without any promise or any assurance that they shall obtain them. No being able to grant them has promised them; no one has assured them that their lives shall be lengthened out to obtain them. In a moment they may be cut off and all their plans frustrated; or they may be utterly disappointed and all their plans fail; or if they gain the object, it may be unsatisfactory, and may furnish no pleasure such as they had anticipated. But not so the Christian. He has:

(1) The promise of life.

(2) he has the assurance that sudden death cannot deprive him of it. It at once removes him to the object of pursuit, not from it.

(3) he has the assurance that when obtained, it shall not disgust, or satiate, or decay, but that it shall meet all the expectations of the soul, and shall be eternal.

Not by sight - This may mean either that we are not influenced by a sight of these future glories, or that we are not influenced by the things which we see. The main idea is, that we are not influenced and governed by the sight. We are not governed and controlled by the things which we see, and we do not see those things which actually influence and control us. In both it is faith that controls us, and not sight.

For we walk by faith - While we are in the present state faith supplies the place of direct vision. In the future world we shall have sight - the utmost evidence of spiritual and eternal things; as we shall be present with them, and live in them. Here we have the testimony of God, and believe in their reality, because we cannot doubt his word. And to make this more convincing he gives us the earnest of his Spirit, which is a foretaste of glory.

For we walk by faith, and not by sight. Faith is a grace which answers many useful purposes; it is the eye of the soul, by which it looks to Christ for righteousness, peace, pardon, life, and salvation; the hand by which it receives him, and the foot by which it goes to him, and walks in him as it has received him; which denotes not a single act of faith, but a continued course of believing; and is expressive, not of a weak, but of a strong steady faith of glory and happiness, and of interest in it: and it is opposed to "sight": by which is meant, not sensible communion, but the celestial vision: there is something of sight in faith; that is a seeing of the Son; and it is an evidence of things not seen, of the invisible glories of the other world; faith looks at, and has a glimpse of things not seen, which are eternal; but it is but seeing as through a glass darkly; it is not that full sight, face to face, which will be had hereafter, when faith is turned into vision.

By sight (διὰ εἴδους)

The correct rendering is appearance. The word is not used actively in the sense of vision. Faith is contrasted with the actual appearance of heavenly things. Hence the marginal reading of the Rev. should go into the text.

(For we walk by {e} faith, not by sight:)

(e) Faith, of those things which we hope for, not having God presently in our physical view.

5:7 For we walk by faith, not by sight. It is by faith here that we see the Lord, though absent from him.

5:7 For we cannot clearly see him in this life, wherein we walk by faith only: an evidence, indeed, that necessarily implies a kind of seeing him who is invisible; yet as far beneath what we shall have in eternity, as it is above that of bare, unassisted reason.

7. we walk-in our Christian course here on earth.

not by sight-Greek, "not by appearance." Our life is governed by faith in our immortal hope; not by the outward specious appearance of present things [Tittmann, Greek Synonyms of the New Testament]. Compare "apparently," the Septuagint, "by appearance," Nu 12:8. Wahl supports English Version. 2Co 4:18 also confirms it (compare Ro 8:24; 1Co 13:12, 13). God has appointed in this life faith for our great duty, and in the next, vision for our reward [South] (1Pe 1:8).

5:1-8 The believer not only is well assured by faith that there is another and a happy life after this is ended, but he has good hope, through grace, of heaven as a dwelling-place, a resting-place, a hiding-place. In our Father's house there are many mansions, whose Builder and Maker is God. The happiness of the future state is what God has prepared for those that love him: everlasting habitations, not like the earthly tabernacles, the poor cottages of clay, in which our souls now dwell; that are mouldering and decaying, whose foundations are in the dust. The body of flesh is a heavy burden, the calamities of life are a heavy load. But believers groan, being burdened with a body of sin, and because of the many corruptions remaining and raging within them. Death will strip us of the clothing of flesh, and all the comforts of life, as well as end all our troubles here below. But believing souls shall be clothed with garments of praise, with robes of righteousness and glory. The present graces and comforts of the Spirit are earnests of everlasting grace and comfort. And though God is with us here, by his Spirit, and in his ordinances, yet we are not with him as we hope to be. Faith is for this world, and sight is for the other world. It is our duty, and it will be our interest, to walk by faith, till we live by sight. This shows clearly the happiness to be enjoyed by the souls of believers when absent from the body, and where Jesus makes known his glorious presence. We are related to the body and to the Lord; each claims a part in us. But how much more powerfully the Lord pleads for having the soul of the believer closely united with himself! Thou art one of the souls I have loved and chosen; one of those given to me. What is death, as an object of fear, compared with being absent from the Lord!
