The concept of my God, with the emphasis on MY is something believers would do well to give more attention to as God is so many different things to different people. In my interactions, it's quite common that people paint God as benefactor that has designed existence for the good of the specific believer. This god is a creation of the desires of the believer as opposed to what is written in the Biblical text and this egocentrically created god is more prevailent than Bible God in our society. So many will assert they know God, (and I suppose they do because he's a mental construction in their respective minds), but have no to very little familiarity with the scriptures.
