The imagery of the vine is ancient, as the Old Testament portrays Israel as God’s vine. But Israel proved to be a fruitless, unfaithful vine, and their apostasy made it disqualified as the channel for God’s blessing. Those blessings now come only from union with Jesus Christ, the true vine. Theologically, the point of John 15:1-5 is that Jesus displaces Israel as the focus of God’s plan of salvation. The implication is that faith in Jesus becomes the decisive characteristic for membership among God’s people. The point of this analogy is not to define the relationship of the father to the Son, but to emphasize the Father’s care for the vine and the branches.
There are many who have a false profession of faith, the evidence lies in whether or not shoes professing ranches bear fruit (Galatians 5:22-23). Knowing the truth, Orthodoxy, is not proof of salvation, proof of salvation comes manifesting the fruit of the Spirit in our lives. The lack of love in the church today, is a reflection of the worldliness and carnality of the Christians who comprise it. We need to examine our lives and see if we have life, and fruit, and if the source of that life is from the Spirit of God within us. Remember the branch is not responsible for pruning itself, nor is the branch responsible fro other branches, the branch is only responsible for allowing the vinedresser to do the work on it and through it that He determines.
