Luke 11:9-13  NAS

"So I say to you, ask, and it will be given to 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.  Now suppose one of you fathers is asked by his son for a fish; he will not give him a snake instead of a fish will he?  Or if he is asked for and egg, he will not give him a scorpion, will he?  If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him?"
