Why Pray (In Public)?

Hebrews 10:23 Let us hold tightly without wavering to the hope we affirm, for God can be trusted to keep his promise. 24 Let us think of ways to motivate one another to acts of love and good works. 25 And let us not neglect our meeting together, as some people do, but encourage one another, especially now that the day of his return is drawing near.

Acts 12:5 But while Peter was in prison, the church prayed very earnestly for him.
6 The night before Peter was to be placed on trial, he was asleep, fastened with two chains between two soldiers. Others stood guard at the prison gate. 7 Suddenly, there was a bright light in the cell, and an angel of the Lord stood before Peter. The angel struck him on the side to awaken him and said, “Quick! Get up!” And the chains fell off his wrists. 8 Then the angel told him, “Get dressed and put on your sandals.” And he did. “Now put on your coat and follow me,” the angel ordered.
9 So Peter left the cell, following the angel. But all the time he thought it was a vision. He didn’t realize it was actually happening. 10 They passed the first and second guard posts and came to the iron gate leading to the city, and this opened for them all by itself. So they passed through and started walking down the street, and then the angel suddenly left him.
11 Peter finally came to his senses. “It’s really true!” he said. “The Lord has sent his angel and saved me from Herod and from what the Jewish leaders had planned to do to me!”
12 When he realized this, he went to the home of Mary, the mother of John Mark, where many were gathered for prayer. 13 He knocked at the door in the gate, and a servant girl named Rhoda came to open it. 14 When she recognized Peter’s voice, she was so overjoyed that, instead of opening the door, she ran back inside and told everyone, “Peter is standing at the door!”
15 “You’re out of your mind!” they said. When she insisted, they decided, “It must be his angel.”
16 Meanwhile, Peter continued knocking. When they finally opened the door and saw him, they were amazed.

Matthew 18:18 “I tell you the truth, whatever you forbid on earth will be forbidden in heaven, and whatever you permit on earth will be permitted in heaven. 19 “I also tell you this: If two of you agree here on earth concerning anything you ask, my Father in heaven will do it for you. 20 For where two or three gather together as my followers, I am there among them.”
