The document discusses persistence in prayer based on two passages from the Bible. It notes that Jesus tells a parable about a man who persistently asks his friend for bread late at night. Even though the friend refuses at first, he gets up and gives the man what he needs because of his persistence. The document then quotes another passage where Jesus says those who ask will receive, those who seek will find, and those who knock will have the door opened. This implies that believers should persist in prayer.
