John 15:5

I am the vine, ye are the branches. — The first clause is repeated to bring out the contrast with the second. It has been implied, but not directly stated, that they are the branches. It may be that there was a pause after the end of the fourth verse, accompanied by a look at the disciples, or at that which suggested the imagery of the vine. His words would then continue with the sense, “Yes, it is so. That is the true relation between us. I am the vine, ye are the branches. The fruitful branches represent men that abide in Me...”

For without me ye can do nothing. — Better, separate from Me, or, apart from Me. (Comp. margin.) The words bring out the fulness of the meaning of the fruitfulness of the man who abides in Christ. It is he, and he only, who brings forth fruit, for the man who is separate from Christ can bear no fruit. The words have often been unduly pressed, to exclude all moral power apart from Christ, whereas the whole context limits them to the fruit-bearing of the Christian life. The persons thought of all through this allegory are true and false Christians, and nothing is said of the influence on men of the wider teaching of God, the Light of the Logos ever in the world. A moral power outside the limits of Christianity is clearly recognised in the New Testament. (Comp., e.g., Romans 2:14, Notes.)
