Man in his attempt to worship God, established a ritual, practice, religion to fulfill that purpose. Did God really want us to form a religion? I don't think so. He wanted a personal relationship with us. He had it with Adam, Eve, Enoch, Abraham, Moses, the Old Testament prophets. Ultimately he sent his Son, Jesus to do that as well - he lived with us, felt as one of us, wept as one of us (and with us) and died for us in order to restore that relationship back to God. It's a matter of the heart.
