"“Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you.”— Matthew 7:7 . To leave no chance for unbelief, misunderstanding, or misinterpretation of His words, the Lord repeats the thrice-given promise. He longs to have those who would seek after God believe in Him who is able to do all things. Therefore He adds, “For everyone that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.” MB 130"
"Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:"
