After Jesus rises from the dead, he spends a few weeks hanging out with his followers. He tells then to stay in Jerusalem, waiting for a surprise Father God has planned for them: the gift of the Holy Spirit to come upon them and give them power.
They wait and the Holy Spirit shows up. Amazing things happen, and the number of Jesus’ followers explodes.
They waited in Jerusalem as instructed, and they received the gift of Holy Spirit power as promised. After all that, they remain in Jerusalem. They are supposed to spread out and spread the word; Jesus told them to do that, too. But they don’t; they stay where they are.
They don’t seem to realize that Jesus’ instruction to wait in Jerusalem doesn’t mean they’re supposed to stay there forever.
Sometimes what God tells us to do is only for a season. Then there’s something else for us to do. But if we don’t make that transition, we end up being in the wrong place, doing the wrong thing.
