I am the vine and you are the branches. The one who remains in Me, and I in him, will bear much fruit. For apart from Me you can do nothing. -John 15:5
Jesus has to spell it out! He wants us to clearly understand who is who. We are just the branches, He is the vine. Just in case we forget it and lose our perspective, He’s reminding us! The life comes from the vine, the life comes from Jesus, and we can do nothing apart from Him.
