In which Gospel is "The vine" explicitly referenced?

The reference to "The vine" is explicitly found in the Gospel of John, specifically in John 15, where Jesus describes Himself as the true vine and His followers as the branches. This metaphor emphasizes the relationship between Christ and believers, illustrating the idea of reliance on Him for spiritual sustenance and growth. In this passage, Jesus teaches that apart from Him, His followers can do nothing, stressing the importance of remaining in Him for fruitful living. The imagery of the vine is uniquely significant in John’s narrative compared to the other Gospels, which do not provide this specific metaphorical description.

Understanding this context enhances one’s appreciation of the theological themes present in John's Gospel, particularly around the concepts of connection, productivity in faith, and the nature of discipleship.
