Expositor's Bible Commentary Commentary John 15:5

"I am the vine, ye are the branches: He that abideth in me, and I in him, the same beareth much fruit: for apart from me ye can do nothing." — John 15:5 (ASV)

Fruitbearing is not only possible but certain if the branch remains in union with the vine, though uniformity of quantity and quality is not promised. But if the life of Christ permeates a disciple, fruit will be inevitable.
