Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. (Matthew 7:7-8)
It is significant that the Lord thought it necessary to repeat the truth in so many forms. It proves that He knows our hearts, how doubt and distrust toward God are natural to us, and how easily we are inclined to rest in prayer as a religious duty without expecting an answer.
