Without doubt the mightiest thought the mind can entertain is the thought of God....That our idea of God correspond as nearly as possible to the true being of God is of immense importance....A right conception of God is basic not only to systematic theology but to practical Christian living as well. It is to worship what the foundation is to the temple; where it is inadequate or out of plumb the whole structure must sooner or later collapse. I believe there is scarcely an error in doctrine or a failure in applying Christian ethics that cannot be traced finally to imperfect and ignoble thoughts about God....
The man who comes to a right belief about God is relieved of ten thousand temporal problems, for he sees at once that these...cannot concern him for very long; but...the one mighty single burden of eternity begins to press down upon him with a weight more crushing than all the woes of the world piled one upon another. That mighty burden is his obligation...to love God with every power of mind and soul, to obey Him perfectly, and to worship Him acceptably....
Among the sins to which the human heart is prone, hardly any other is more hateful to God than idolatry....The essence of idolatry is the entertainment of thoughts about God that are unworthy of Him....The heaviest obligation lying upon the Christian Church today is to purify and elevate her concept of God until it is once more worthy of Him—and of her.
