The Upper Room Prayer Meeting
12 Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a Sabbath day’s journey. 13 And when they had entered, they went up into the upper room where they were staying: Peter, James, John, and Andrew; Philip and Thomas; Bartholomew and Matthew; James the son of Alphaeus and Simon the Zealot; and Judas the son of James. 14 These all continued with one [d]accord in prayer [e]and supplication, with the women and Mary the mother of Jesus, and with His brothers.
Matthias Chosen
15 And in those days Peter stood up in the midst of the [f]disciples (altogether the number of names was about a hundred and twenty), and said, 16 “Men and brethren, this Scripture had to be fulfilled, which the Holy Spirit spoke before by the mouth of David concerning Judas, who became a guide to those who arrested Jesus; 17 for he was numbered with us and obtained a part in this ministry.”
18 (Now this man purchased a field with the [g]wages of iniquity; and falling headlong, he burst open in the middle and all his [h]entrails gushed out. 19 And it became known to all those dwelling in Jerusalem; so that field is called in their own language, Akel Dama, that is, Field of Blood.)
20 “For it is written in the Book of Psalms:
‘Let his dwelling place be [i]desolate,
And let no one live in it’;
and,
‘Let another take his [j]office.’
21 “Therefore, of these men who have accompanied us all the time that the Lord Jesus went in and out among us, 22 beginning from the baptism of John to that day when He was taken up from us, one of these must become a witness with us of His resurrection.”
23 And they proposed two: Joseph called Barsabas, who was surnamed Justus, and Matthias. 24 And they prayed and said, “You, O Lord, who know the hearts of all, show which of these two You have chosen 25 to take part in this ministry and apostleship from which Judas by transgression fell, that he might go to his own place.” 26 And they cast their lots, and the lot fell on Matthias. And he was numbered with the eleven apostles.
Good morning and welcome
Our Father which art in heaven, Hallowed be thy name.
Thy kingdom come, Thy will be done in earth, as it is in heaven.
Give us this day our daily bread.
And forgive us our debts, as we forgive our debtors.
And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, forever. Amen
