In John 15:18-25, Jesus shifts the focus from the joy and fruitfulness of abiding in Him to the reality of opposition His followers will face. He prepares His disciples for the inevitable hatred and persecution they will experience because of their association with Him. Jesus makes it clear that this hostility from the world is not a reflection of the disciples themselves but a result of the world's rejection of Him.

In John 15, Jesus introduces the powerful metaphor of the vine and branches to illustrate the essential nature of our relationship with Him. Jesus, as the true vine, is the source of life, strength, and fruitfulness for His followers, who are the branches. The Father, as the gardener, lovingly prunes and cares for the vine so that it may flourish. For the branches, the key to bearing fruit is remaining or abiding in the vine—staying connected to Jesus.
