The document is a sermon about the importance of persistent prayer based on the parable of the persistent widow from Luke 18:1-8. The parable tells of a widow who repeatedly asks an unjust judge for justice against her enemy until he grants it just to end her constant requests. Jesus says that if even the unjust judge will grant justice due to persistence, how much more will God, who is just, grant justice to His people who cry out to Him day and night. The sermon encourages believers to pray persistently and never give up hope that God will answer their prayers.
