The Gospel According to Luke 11:9-13
The Lord said to his disciples, "Ask, and it will be given you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened. What father among you, if his son asks for bread, will give him a stone; or if he asks for a fish, will instead of a fish give him a serpent; or if he asks for an egg, will give him a scorpion? If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!"
