John the Apostle
John 15:4BSB·traditional attribution

Remain in Me, and I will remain in you. Just as no branch can bear fruit by itself unless it remains in the vine, neither can you bear fruit unless you remain in Me.

Jamieson-Fausset-Brown Reformed

All spiritual fruitfulness flows from the vital, living interpenetration of Christ and His disciples. This living connection must be kept up; without it, fruitfulness ceases.

AI summary

John Gill Reformed Baptist

The branch and vine express our sameness of nature with Christ and our strict union to Him, through which life, grace, and strength flow to us. Without Him we can do nothing spiritually good, not even think one good thought or speak one good word.

AI summary

John Calvin Reformed

Christ exhorts us to abide in Him because the flesh is careless and indifferent, we need constant stirring. He promises His Spirit will work efficaciously in us, if we do not hinder Him; all who have a living root in Him bear much fruit.
