Then came the Day of Unleavened Bread, when the Passover must be killed. And He [Jesus] sent Peter and John, saying, “Go and prepare the Passover for us, that we may eat.” So they said to Him, “Where do You want us to prepare?” And He said to them, “Behold, when you have entered the city, a man will meet you carrying a pitcher of water; follow him into the house which he enters. Then you shall say to the master of the house, ‘The Teacher says to you, “Where is the guest room where I may eat the Passover with My disciples?”‘ “Then he will show you a large, furnished upper room; there make ready” (Luke 22: 7-12, NKJV).
I went to the Upper Room with a group from my congregation several weeks ago. It was my first trip to Israel, and to stand in the very place where Jesus shared the Last Supper with his disciples was overwhelming. Of course, the Upper Room looks different than it did 2000 years ago. The architecture of the present-day Upper Room dates from the time of the Crusades. The design on the column in the last photo (below) is unique and appears to be older than the other columns in the room.
The “tree” in the room was placed there to convey the concept of Jew and Gentile one in Messiah, the Gentiles having been “grafted in” (Romans 11: 13-24).
It is believed that the Baptism of the Holy Spirit took place in this same room on the day of Pentecost (a.k.a. Shavuot or Feast of Weeks).
When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them (Acts 2: 1-4, NIV).
