1 John 1:7

7. Compare Ep 5:8, 11-14. "We walk"; "God is (essentially in His very nature as 'the light,' 1Jo 1:5) in the light." Walking in the light, the element in which God Himself is, constitutes the test of fellowship with Him. Christ, like us, walked in the light (1Jo 2:6). Alford notices, Walking in the light as He is in the light, is no mere imitation of God, but an identity in the essential element of our daily walk with the essential element of God's eternal being. we have fellowship one with another--and of course with God (to be understood from 1Jo 1:6). Without having fellowship with God there can be no true and Christian fellowship one with another (compare 1Jo 1:3). and--as the result of "walking in the light, as He is in the light." the blood of Jesus ... cleanseth us from all sin--daily contracted through the sinful weakness of the flesh, and the power of Satan and the world. He is speaking not of justification through His blood once for all, but of the present sanctification ("cleanseth" is present tense) which the believer, walking in the light and having fellowship with God and the saints, enjoys as His privilege. Compare Joh 13:10, Greek, "He that has been bathed, needeth not save to wash his feet, but is clean every whit." Compare 1Jo 1:9, "cleanse us from all unrighteousness," a further step besides "forgiving us our sins." Christ's blood is the cleansing mean, whereby gradually, being already justified and in fellowship with God, we become clean from all sin which would mar our fellowship with God. Faith applies the cleansing, purifying blood. Some oldest manuscripts omit "Christ"; others retain it.

Verse 7. But if we walk in the light. 1Jn 1:5. Walking in the light may include the three following things:

(1.) Leading lives of holiness and purity; that is, the Christian must be characteristically a holy man, a light in the world, by his example.

(2.) Walking in the truth; that is, embracing the truth in opposition to all error of heathenism and infidelity, and having clear, spiritual views of truth, such as the unrenewed never have. See 2Cor 4:6, 1Cor 2:9-15; Eph 1:18.

(3.) Enjoying the comforts of religion; that is, having the joy which religion is fitted to impart, and which it does impart to its true friends, Ps 94:19, Isa 57:8, 2Cor 1:3, 13:11. Jn 12:35.

As he is in the light. In the same kind of light that he has. The measure of light which we may have is not the same in degree, but it is of the same kind. The true Christian in his character and feelings resembles God.

We have fellowship one with another. As we all partake of his feelings and views, we shall resemble each other. Loving the same God, embracing the same views of religion, and living for the same ends, we shall of course have much that is common to us all, and thus shall have fellowship with each other.

And the blood of Jesus Christ his Son cleanseth us from all sin. See the sentiment here expressed fully explained Heb 9:11. When it is said that his blood cleanses us from all sin, the expression must mean one of two things--either that it is through that blood that all past sin is forgiven, or that that blood will ultimately purify us from all transgression, and make us perfectly holy. The general meaning is plain, that in regard to any and every sin of which we may be conscious, there is efficacy in that blood to remove it, and to make us wholly pure. There is no stain made by sin so deep that the blood of Christ cannot take it entirely away from the soul. The connexion here, or the reason why this is introduced here, seems to be this: The apostle is stating the substance of the message which he had received, 1Jo 1:5. The first or leading part of it was, that God is light, and in him is no darkness, and that his religion requires that all his friends should resemble him by their walking in the light. Another, and a material part of the same message was, that provision was made in his religion for cleansing the soul from sin, and making it like God. No system of religion intended for man could be adapted to his condition which did not contain this provision, and this did contain it in the most full and ample manner. Of course, however, it is meant that that blood cleanses from all sin only on the conditions on which its efficacy can be made available to man--by repentance for the past, and by a cordial reception of the Saviour through faith.

(b) "walk" Jn 12:35 (c) "blood" Eph 1:7, Heb 9:14, 1Pet 1:19, Rev 1:5

Verse 7 But if we walk in the light - If, having received the principle of holiness from him, we live a holy and righteous life, deriving continual light, power, and life from him, then we have fellowship one with another; that is, we have communion with God, and God condescends to hold communion with us. This appears to be the intention of the apostle; and so he was understood by some versions and MSS., which, instead of μετ' αλληλων, with each other, have μετ' αυτον, with him. Those who are deeply experienced in Divine things converse with God, and God with them. What John says is no figure; God and a holy heart are in continual correspondence. The blood of Jesus Christ - The meritorious efficacy of his passion and death has purged our consciences from dead works, and cleanseth us, καθαριζει ἡμας, continues to cleanse us, i.e., to keep clean what it has made clean, (for it requires the same merit and energy to preserve holiness in the soul of man, as to produce it), or, as several MSS. and some versions read, καθαριει and καθαρισει, will cleanse; speaking of those who are already justified, and are expecting full redemption in his blood. And being cleansed from all sin is what every believer should look for, what he has a right to expect, and what he must have in this life, in order to be prepared to meet his God. Christ is not a partial Savior, he saves to the uttermost, and he cleanses from All sin.
