The effect of righteous man’s prayer

Acts 12:5-11

5  So Peter was kept in prison, but the church was earnestly praying to God for him.

6  The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance.

7  Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and the chains fell off Peter's wrists.

8  Then the angel said to him, “Put on your clothes and sandals.” And Peter did so. “Wrap your cloak around you and follow me,” the angel told him.

9  Peter followed him out of the prison, but he had no idea that what the angel was doing was really happening; he thought he was seeing a vision.

10  They passed the first and second guards and came to the iron gate leading to the city. It opened for them by itself, and they went through it. When they had walked the length of one street, suddenly the angel left him.

11  Then Peter came to himself and said, “Now I know without a doubt that the Lord sent his angel and rescued me from Herod's clutches and from everything the Jewish people were anticipating.”

Acts 10:38 

how God anointed Jesus of Nazareth with the Holy Spirit and power, and how he went around doing good and healing all who were under the power of the devil, because God was with him.

Acts 4:24-31

24  When they heard this, they raised their voices together in prayer to God. “Sovereign Lord,” they said, “you made the heaven and the earth and the sea, and everything in them.

25  You spoke by the Holy Spirit through the mouth of your servant, our father David: “‘Why do the nations rage and the peoples plot in vain?

26  The kings of the earth take their stand and the rulers gather together against the Lord and against his Anointed One.’

27  Indeed Herod and Pontius Pilate met together with the Gentiles and the people of Israel in this city to conspire against your holy servant Jesus, whom you anointed.

28  They did what your power and will had decided beforehand should happen.

29  Now, Lord, consider their threats and enable your servants to speak your word with great boldness.

30  Stretch out your hand to heal and perform miraculous signs and wonders through the name of your holy servant Jesus.”

31  After they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly.
