In the Upper Room, on the night before he died, Jesus kept telling his disciples that he had to leave them and would send them the Advocate, another name for the Holy Spirit. In fact, he told them, “But I tell you the truth, it is better for you that I go. For if I do not go, the Advocate will not come to you” (John 16:7). The Holy Spirit, fully revealed at Pentecost, comes to the apostles in the Upper Room only because of Jesus’s departure.
