Your sort of argument asks the believer to step out of his beliefs. This is an impossibility unless one's reasoning ability is so defective that it is somehow able to disconnect properly basic presuppositions, e.g., God exists, from themselves. My mind is unable to apprehend God without being compelled to honor Him. It is not sufficient to hold that there is a God that we all ought to honor and adore, unless we are also persuaded that He is the source of every good, and that we must seek nothing elsewhere than in Him.

What good is it to speculate some sort of God who has cast aside the care of the world only to amuse Himself in idleness? In short, what help is it to know a God with whom we have nothing to do? Instead, our knowledge should serve first to teach us fear and reverence. With it as our guide and teacher, we should learn to seek every good from God, and, having received it, to credit it to His account.

How is it that even the thought of God penetrating your mind is not accompanied by the immediate realization that since you were created by God, you have been fashioned and bound to His command by God's right of creation, that you owe your life to God? In other words, by owing your life to God, whatever you aims in life are, whatever you do, they all ought to be attributed to God.

If this is true, it certainly follows that your life (your aims and acts) is wickedly corrupt unless your life is disposed to God's service given that God's revealed will ought for us to be the law by which we live. You cannot behold God clearly unless you acknowledge Him to be the originating source of every good. Given this, the desire to cling to God and trust in Him becomes apparent, except for the fact that man's depravity seduces His mind from rightly seeking God.
