12 When this had dawned on him, he went to the house of Mary the mother of John, also called Mark, where many people had gathered and were praying. 13 Peter knocked at the outer entrance, and a servant named Rhoda came to answer the door. 14 When she recognized Peter’s voice, she was so overjoyed she ran back without opening it and exclaimed, “Peter is at the door!”15 “You’re out of your mind,” they told her. When she kept insisting that it was so, they said, “It must be his angel.”16 But Peter kept on knocking, and when they opened the door and saw him, they were astonished. 17 Peter motioned with his hand for them to be quiet and described how the Lord had brought him out of prison. “Tell James and the other brothers and sisters about this,” he said, and then he left for another place.18 In the morning, there was no small commotion among the soldiers as to what had become of Peter. 19 After Herod had a thorough search made for him and did not find him, he cross-examined the guards and ordered that they be executed. Then Herod went from Judea to Caesarea and stayed there.
When Peter escaped, he made his way straight to the house of Mary, the mother of John Mark. Note what the Disciples were doing. They were praying. When they were up against it, they turned to God.
In this passage, we have the first mention of the man who was the real leader of the Church in Jerusalem. During Jesus lifetime, James was not a supporter of Jesus. But the risen Christ made a special appearance to James. The change in James may well be another great example of the power of the cross to change human lives.
