Question 1

What does John 17:21 mean?

Accepted Answer

John 17:21 records Jesus praying that all his followers would be united as one, just as he and the Father are united, so that the world may believe that God sent him. Jesus is asking for a deep, spiritual unity among believers that reflects the close relationship he shares with God the Father. In this verse, Jesus is speaking to God the Father during what is often called his "High Priestly Prayer," just before his arrest. He is not talking to the disciples directly, but praying for them and for all future believers. The unity Jesus describes is meant to be so real and visible that it serves as a testimony to the world about who he is and why he was sent.

The Greek behind John 17:21

Accepted Answer

ἓν (hen, "one"): This word means "one" in the sense of unity or oneness, not just a group acting together but a deep, shared life and purpose. Jesus is praying for a unity among believers that mirrors the unity between himself and the Father. ἐν (en, "in"): This preposition means "in" or "within," and here it highlights the closeness of the relationship—Jesus in the Father, the Father in Jesus, and believers being "in" them. It points to a spiritual closeness, not just agreement or cooperation. πιστεύσῃ (pisteusē, "may believe"): This verb means "to believe" or "to trust." Jesus connects the unity of his followers to the world's ability to believe that he was sent by God, showing that their unity has a purpose beyond themselves.
