Acts 12:5, 12-15

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

"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. Peter knocked at the outer entrance, and a servant named Rhoda came to answer the door. When she recognized Peter’s voice, she was so overjoyed she ran back without opening it and exclaimed, “Peter is at the door!”

“You’re out of your mind,” they told her. When she kept insisting that it was so, they said, “It must be his angel.”

Those gathered were fervently praying for something that their mind couldn't fully comprehend. So when they got the answer to their prayer, they could barely believe it. We don't have to understand how God is going to solve what in the natural seems impossible, our role is only to fervently pray and watch God blow our minds!
