He does not want to be God's friend. God calls this stubbornness. This rebellion against Him is sin. You get what is coming to you when you sin. God is holy.
Man is sinful.
There is a big canyon that separates God and man. People try to reach God in many ways, such as traditional or formal religion, or by trying to life a good life. Jesus Christ is God's only answer for man's sin. It is only through Jesus that we can know God as a true Friend. You can know His love.
