When a man is on his death bed, you can probably assume that his final words are going to be very important to him. He's not going to waste his breath on trivial things, rather he will want to open his heart and speak his final thoughts. When our Lord was about to go to the cross, what was on His heart? The relationship between a vine and branches. What does that have to do with us? Actually everything! If we see our relationship in this light, then God can have a way to gain what He is after on this earth.
