In Acts 12, we see Peter imprisoned, chained and surrounded by guards. Through the church's earnest prayer, God began to deliver him. Chains fell to the ground, doors and gates swung open, but Peter was required to step through. When God's part was done, the angel departed, but Peter encountered another gate—one that did not supernaturally swing open. There is a part that God plays in bringing freedom to the captives, but He also invites and asks us to open the last gate by faith.
