"They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers." (Acts 1:14 )

The book of Acts starts with the wonderful period of Jesus’ resurrection appearances, where he proves to his numerous disciples that he was truly raised from the dead. But then, Jesus leaves and ascends to heaven. Before doing so what does he tell the disciples to do? To wait. They are to stay in Jerusalem until they receive the gift of the Holy Spirit, which will enable them to witness powerfully to the reality of Jesus’ resurrection (Acts 1:4,8).
