Some explanation please

I was reading some of Denver's Study Guides and he was referencing Matthew 7.I like this two chapters;Matthew 7:7-8Ask, 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.I like them cause I took them as meaning If one ask GOD to come into there life he would.But now after reading Denver's Study Guides I think I might be wrong. He did not mention verse 7 and 8 but verse 6 and 9 are noting talking about this.Could someone please talk more about them please?Thanks,Tommy
