Our relation to God is unrighteous. Secretly we are ourselves the masters in this relationship. We are not concerned with God, but with our own requirements, to which God must adjust Himself. Our arrogance demands that, in addition to everything else, some super-world should also be known and accessible to us. Our conduct calls for some deeper sanction, some approbation and remuneration from another world.
Our well-regulated, pleasurable life longs for some hours of devotion, some prolongation into infinity. And so, when we set God upon the throne of the world, we mean by God ourselves. In "believing" on Him, we justify, enjoy, and adore ourselves.
-- Karl Barth, The Epistle to the Romans
