John 15:4-5

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
Verse 5. I am the vine, Jn 15:1

Without me ye can do nothing. The expression "without me" denotes the same as separate from me. As the branches, if separated from the parent stock, could produce no fruit, but would immediately wither and die, so Christians, if separate from Christ, could do nothing. The expression is one, therefore, strongly implying dependence. The Son of God was the original source of life, Jn 1:4. He also, by his work as Mediator, gives life to the world (Jn 6:33), and it is by the same grace and agency that it is continued in the Christian. We see hence,

1st. That to him is due all the praise for all the good works the Christian performs.

2nd. That they will perform good works just in proportion as they feel their dependence on him and look to him. And

3rd. That the reason why others fail of being holy is because they are unwilling to look to him, and seek grace and strength from him who alone is able to give it.

(1) "without me", or "severed from me"
