What does the Bible say about Jesus as the true vine?

In John 15:1, Jesus declares, 'I am the true vine.' This statement emphasizes His essential role as the source of spiritual life and nourishment for believers. As the true vine, He contrasts Himself with false vines, which do not provide genuine sustenance. His followers, depicted as branches, are reminded that apart from Him, they can do nothing (John 15:5). This metaphor underscores that true life and fruitfulness can only flow from a genuine relationship with Christ, who is perfect and wholly sufficient.
