John 15: Jesus is the true vine, we are the branches. The Tree of the Knowledge of Good and Evil brings death. Dead branches come from that tree. Apart from God we can do nothing (lasting or life-giving). Jesus came to give us LIFE and life abundant. He is the Tree of Life. We are grafted in (an unfruitful branch is grafted into the life-giving vine) so that we have HIS life flowing through us, producing life-giving fruit for us and others.
