Matthew 7:7-8 from the Bible's Sermon on the Mount encourages persistent prayer and seeking God, stating, "Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives, and the one who seeks finds, and to the one who knocks it will be opened," emphasizing God's willingness to give good things to those who ask, just as earthly parents give good gifts to their children.
