Acts 1:13 Meaning and Explanation

An upper room, a hidden place of prayer and waiting. Eleven apostles are named; Judas Iscariot is conspicuously absent, already dead. The list is almost casual—Peter, James, John, Andrew, Philip, Thomas, Bartholomew, Matthew, James the Less, Simon the Zealot, Judas (not Iscariot). These are the ordinary men who will turn the world upside down. We know some by reputation—Peter the rock, Thomas the doubter, Matthew the tax-collector. Others are barely mentioned in the Gospels; their names are all we know. Yet all are chosen, all have been with Jesus, all are waiting together. The upper room becomes the womb of the church, the place where God's new people are gestating in prayer.

Notice the unanimity: they went up together, they abode in one place. This is not a gathering of individual seekers but a community united by their shared experience of Jesus and their obedience to his command. Later, Paul will write of the church as the body of Christ; here in the upper room we see that body forming, waiting, praying. For us, the church is still that: ordinary people called together by Christ, united in waiting for his Spirit, empowered to change the world.
