Verse 7. For we walk. To walk, in the Scriptures, often denotes to live, to act, to conduct [one's self] in a certain way. See Barnes "Ro 4:12"; See Barnes "Ro 6:4".

It has reference to the fact that life is a journey, or a pilgrimage, and that the Christian is travelling 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, honour, splendour, 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 Barnes "Mr 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 men 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 honour and wealth which are unseen, and which are 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 labour, 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 labour, 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 men 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.
