(56) Dwelleth in me, and I in him.--Abideth gives the sense more fully. (Comp. John 14:2-23; John 15:4 et seq.; John 17:23; 1John 3:24; 1John 4:16.) It is one of those deeper thoughts which meet us only in the words of the beloved disciple. The union which results from the communication of life is not temporary, but is one that remaineth. By virtue of it we abide in Christ, and He in us. It is our home life, that of every day, and will be the life of the eternal home (John 14:2). (Comp. Note on John 5:38, and the contrast in John 3:36.)

Verse 56. - He that eateth my flesh and drinketh my blood, dwelleth in me, and I (dwell) in him. This mutual indwelling is illustrated elsewhere (John 15:1-5) by the image of the vine and its branches. The vine abides in the branch in the virtue of its life-giving forces. Cut away from the parent stem, it can do nothing. Fruitlessness condemns and fire consumes it. The branch abides in the vine, as deriving all its worth, its true place, its possibility of growth and fruit, from the vine (cf. also John 17:23; 1 John 3:24; 1 John 4:16). The dwelling of the believer in Christ involves an utter self-surrender to him, a recognition of the supreme claims of the God-Man and his work, a complete trust in him as the Source of all life, a sound and abiding place of rest, a justification before God as one with Christ, as one identified with him in his well pleasing to the Father. The dwelling of Christ in the believer is the fulness and riches of the Divine life. Christ liveth in him (Galatians 2:20), thinks in his thoughts, moves through his will. This is sanctification. The believer is in Christ as the members are in the body. Christ is in the believer as God is in his temple. What is the condition of this mutual indwelling? Christ puts the condition of this Divine interpretation thus: "He that eateth my flesh and drinketh my blood, dwelleth in me, and I in him." The verb is in the present tense, implying the continuous appropriation of the Divine sustenance.

6:52-59 The flesh and blood of the Son of man, denote the Redeemer in the nature of man; Christ and him crucified, and the redemption wrought out by him, with all the precious benefits of redemption; pardon of sin, acceptance with God, the way to the throne of grace, the promises of the covenant, and eternal life. These are called the flesh and blood of Christ, because they are purchased by the breaking his body, and the shedding of his blood. Also, because they are meat and drink to our souls. Eating this flesh and drinking this blood mean believing in Christ. We partake of Christ and his benefits by faith. The soul that rightly knows its state and wants, finds whatever can calm the conscience, and promote true holiness, in the redeemer, God manifest in the flesh. Meditating upon the cross of Christ gives life to our repentance, love, and gratitude. We live by him, as our bodies live by our food. We live by him, as the members by the head, the branches by the root: because he lives we shall live also.He that eateth my flesh, and drinketh my blood,.... In the sense above given; See Gill on John 6:53;

dwelleth in me, and I in him. There is a mutual indwelling of Christ, and believers; Christ is the habitation, or dwelling place of his people: there is a secret dwelling in Christ; so the elect of God dwelt in the heart, and in the hands, and arms of Christ from everlasting; and as members in their head in election grace; and representatively in him, as the Mediator of the covenant; and they secretly and safely dwelt in him, when all mankind fell in Adam; and when he was on the cross, in the grave, and now he is in heaven; all which is owing to his own love, his Father's gift, and to secret union to him. But there is an open dwelling in him in time, which is here meant: God's elect, as in their natural state, are without Christ, and lie open to the law and justice of God; the Spirit of God convinces them of this state, and directs them to flee to Christ, as a city of refuge; when they find him a stronghold, a place of defence, and a proper dwelling for them, where they resolve to abide, and do abide; and where they dwell safely, peaceably, comfortably, and pleasantly; and from which dwelling place they will never be turned out. Likewise, the saints are the habitation or dwelling place of Christ; he dwells not in their heads and to tongues, but in their hearts, and by faith; which is here expressed, by eating his flesh, and drinking his blood; and which, though it is not the cause of Christ's dwelling here, yet is the means or instrument by which men receive him into their hearts, and retain him, and have communion with him; for he dwells in believers, not in such sense as he dwells in the world, by his omnipresence, and power; or in the human nature, by hypostatical union to it; but by his Spirit, and by faith, which is an instance of wonderful condescending grace, and is owing to union to him, and is expressive of communion with him, and is what will continue for ever.
