God is real. He is real in the absolute and final sense that nothing else is. All other reality is contingent upon His.
The great Reality is God the author of that lower and dependent reality which makes up the sum of created things including ourselves. God has objective existence independent of and apart from any notions we have concerning Him.
The worshipping heart does not create its object. It finds Him here when it wakes from its moral slumber in the morning of its regeneration.
