Peter in Prison
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.
Here we see Peter praying while in prison.
Information on the stained glass windows comes from the book "The Windows and Symbolism of First Methodist Church, Birmingham, Michigan", edited by Dr. Arnold F. Runkel and privately published by the church for its members in 1966.
