God of Our Own Making

Question:  Is God a divine accommodation, something or someone we have invented to make us feel good about ourselves, particularly when we know we have done wrong?  Can God be manipulated to get what we want, a kind of divine sugar daddy of the sky?  One to whom we can turn when we need a good cry, or someone to tell us, “What you have done is OK.  You’re not nearly as bad as some”?
