John 15:4

Verse 4. Abide in me. Remain united to me by a living faith. Live a life of dependence on me, and obey my doctrines, imitate my example, and constantly exercise faith in me.

And I in you. That is, if you remain attached to me, I will remain with you, and will teach, guide, and comfort you. This he proceeds to illustrate by a reference to the vine. If the branch should be cut off an instant, it would die and be fruitless. As long as it is in the vine, from the nature of the case, the parent stock imparts its juices, and furnishes a constant circulation of sap adapted to the growth and fruitfulness of the branch. So our piety, if we should be separate from Christ, or if we cease to feel our union to him and dependence on him, withers and droops. While we are united to him by a living faith, from the nature of the case, strength flows from him to us, and we receive help as we need. Piety then, manifested in good works, in love, and self-denial, is as natural, as easy, as unconstrained, and as lovely as the vine covered with fruitful branches is at once useful and enticing.

(f) "abide in me" Jn 2:6 (g) "As the branch" Hoss 14:8, Gal 2:20, Php 1:11

1 John 3:24

Verse 24. And he that keepeth his commandments, etc. Jn 14:23.

And hereby we know that he abideth in us. That is, this is another certain evidence that we are true Christians. The Saviour had promised (Jn 14:23) that he would come and take up his abode with his which people. John says that we have proof that he does this by the Spirit he has given us. That is, the Holy Spirit is imparted to his people to enlighten their minds; to elevate their affections; to sustain them in times of trial; to quicken them in the performance of duty; and to imbue them with the temper and spirit of the Lord Jesus. When these effects exist, we may be certain that the Spirit of God is with us; for these are the "fruits" of that Spirit, or these are the effects which he produces in the lives of men. Comp. Gal 5:22, Gal 5:23. On the evidence of piety here referred to, Rom 8:9, Rom 8:14, Rom 8:16. No man can be a true Christian in whom that Spirit does not constantly dwell, or to whom he is not "given." And yet no one can determine that the Spirit dwells in him, except by the effects produced in his heart and life. In the following chapter, the apostle pursues the subject suggested here, and shows that we should examine ourselves closely, to see whether the "Spirit" to which we trust, as furnishing evidence of piety, is truly the Spirit of God, or is a spirit of delusion.

(f) "he that keepeth" Jn 14:23, 15:10 (g) "hereby" Rom 8:9,14

1 John 4:15-16

Verse 15. Whosoever shall confess that Jesus is the Son of God. In the true sense, and from the heart. This will always prove that a man is a Christian. But the passage cannot mean that if he merely says so in words, or if he does it insincerely, or without any proper sense of the truth, it will prove that he is a Christian. On the meaning of the sentiment here expressed, 1Jn 4:2. Comp. Rom 10:10.

(a) "Whosoever" Rom 10:9
Verse 16. And we have known and believed, etc. We all have assurance that God has loved us, and the fullest belief in the great fact of redemption by which he has manifested his love to us. God is love. 1Jn 4:8. It is not uncommon for John to repeat an important truth. He delights to dwell on such a truth as that which is here expressed; and who should not? What truth is there on which the mind can dwell with more pleasure; what is there that is better fitted to win the heart to holiness; what that will do more to sustain the soul in the sorrows and trials of this life? In our trials; in the darkness which is around us; in the perplexities which meet and embarrass us in regard to the Divine administration; in all that seems to us incomprehensible in this world, and in the prospect of the next, let us learn to repeat this declaration of the favoured disciple, "God is love." What trials may we not bear, if we feel assured of that! What dark cloud that seems to hang over our way, and to involve all things in gloom, will not be bright, if from the depths of our souls we can always say, "God is love!"

And he that dwelleth in love, etc. Religion is all love. God is love; he has loved us; we are to love him; we are to love one another; we are to love the whole world. Heaven is filled with love, and there is nothing else there. The earth is filled with love just as far as religion prevails, and would be entirely if it should prevail everywhere. Love would remove all the corrupt passions, the crimes, the jealousies, the wars on the earth, and would diffuse around the globe the bliss of heaven. If a man, therefore, is actuated by this, he has the spirit of the heavenly world reigning in his soul, and lives in an atmosphere of love.

(b) "God is love" 1Jn 4:8
