John 15:1-8 Jesus Describes His Relationship Both

John 15:1-8 Jesus describes his relationship both to the Father, and also to all Christian believers in John 15:1-8. The passage relies on a central, extended metaphor of Jesus as the Vine of Life. Jesus is the "true vine," tended by the Father as the supreme gardener. God the Father tends to the vine, carefully pruning it and ensuring long-term growth and healthy development of fruit and future branches. Pruning the vine implies removing sin, offering a method of spiritual purification for those who dwell within Jesus.

Jesus as vine represents Jesus as Son, for "Herein is my Father glorified, that ye bear much fruit," (John 15:8). The vine is an extension of the Father, and the Father provides the vine with the sun and nourishment needed for spiritual growth. Moreover, the fruit on the vine symbolizes the disciples: "Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples." The metaphor of bearing fruit can be applied to the individual or collective Christian life.

The passage teaches the reader about Salvation, discipleship, and eternal security as well. Salvation is attained only via abiding fully within Christ. "As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me," (John 15:4). Christ's Word is the only pathway to salvation: "Now ye are clean through the word which I have spoken unto you," (John 15:3). Belief and faith in Christ are prerequisites for salvation, too: "without me ye can do nothing," (John 15: 5).

Those who do not dwell in Christ spiritually die; their branches are "withered," and "men gather them, and cast them into the fire, and they are burned," (John 15:6). Without salvation in Christ, one perishes. Salvation is also explained in terms of God's being able to prune that which is no longer useful or fruitful. "Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit," (John 15:2).

This refers directly to the surrender to God in order to purge one of sins. Discipleship is also a cornerstone of John 15:1-8. Jesus directly refers to his disciples: "Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples," (John 15:8). As the vine of life, Jesus is God glorified and made powerful with purpose on earth. The plan, God's plan, is to ensure that Jesus will "bear much fruit," (John 15:8).

This is not the type of fruitfulness that is expounded upon in the Old Testament, related to fertility and fecundity. Rather, this is symbolic and spiritual fruitfulness. Jesus's work on earth as the vine of life is to produce branches and fruit that create a lasting Christian community, whereby all human beings can find salvation. Discipleship is the ultimate surrender of self to the vine of life: the willingness and ability to "abide in me," as Jesus abides "in you," (John 15:4).

A branch that detaches from the tree (meaning, a person who no longer believes) can never bear fruit. The only method of discipleship is surrender.
