An Upper Room or a Supper Room

And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James the son of Alphaeus, and Simon Zelotes, and Judas the brother of James. These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with His brethren.” 
(Acts 1:13-14) 

Judas Iscariot was noticeably absent, the traitor who betrayed Jesus and took his own life. Noticeably present were the three half brothers of Jesus. James, who wrote the epistle bearing his name, was there. There was Joses. Then there was another half brother of Jesus who was there. Judas, Jude he is called. We have his epistle today. None of those three believed in Jesus during his earthly ministry. But now, there has been a Calvary and an empty tomb. The half brothers now believed. Calvary and the resurrection will make a difference in anyone who will believe.

Someone said, “Our present day Christianity has traded the upper room for a supper room which answers the question of why we are so powerless today.” Jesus had told His disciples to tarry in Jerusalem until they would experience the power of the Holy Spirit upon them. The Holy Spirit has come and has taken up His residence in you when you were saved. You need no other experience.
