A Season Of Unified Expectation
With the apostolic leadership restored to twelve, the atmosphere in the upper room is one of profound, unified expectation. The disciples are not waiting with dread, as they did behind locked doors on Easter weekend. They are waiting with the vibrant, joyful anticipation of men and women who have seen the King conquer death.
Every day that passes brings them closer to the festival of Pentecost. They do not know exactly what the "baptism of the Holy Spirit" will look or sound like, but they are fully surrendered to receiving it. Their unity—"with one mind"—is the crucial prerequisite for the coming rushing mighty wind.
— Acts 1:14
