It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat. – By Theodore Roosevelt

“Do not trust in princes, In mortal man, in whom there is no salvation. His spirit departs, he returns to the earth; In that very day his thoughts perish. How blessed is he whose help is the God of Jacob, Whose hope is in the LORD his God, Who made heaven and earth, The sea and all that is in them; Who keeps faith forever;”
Psalm 146:3–6 (NASB95)

“There is a kind who is pure in his own eyes, Yet is not washed from his filthiness. There is a kind—oh how lofty are his eyes! And his eyelids are raised in arrogance. There is a kind of man whose teeth are like swords And his jaw teeth like knives, To devour the afflicted from the earth And the needy from among men.”
Proverbs 30:12–14 (NASB95)

…one must avoid the opposite mistake of saying that because God has communicated truly concerning science, all scientific study is wasted.  This is a false deduction.  To say that God communicates truly does not mean that God communicates exhaustively.
