Fresh out of jail, having just been miraculously freed by God, Peter goes to the house of John Mark’s mother, where there are a number of people praying for him. These people are encouraged by Peter’s story, and he asks them to spread the story to even more apostles and disciples. The power of testimony is great, and as we share the work Christ has done and continues to do in and through us, we build one another up in the gospel, offering encouragement, hope, and confidence in the Lord.
