On the night before His crucifixion, Jesus says 'I am the true vine.' It is the final I AM statement in John's Gospel, and it captures the entire secret of the Christian life in one image.
This sermon works through John 15:1-5, explaining the roles of the Father as vinedresser, Christ as the vine, and the believer as the branch — and what it practically means to abide in a way that produces fruit.
