This quote from Calvin's Institutes reminds me why we should earnestly strive to know more of God. Hint: it's not to win at Bible-baseball.
The knowledge of God which we are invited to cultivate is not that which, resting satisfied with empty speculation, only flutters in the brain, but a knowledge which will prove substantial and fruitful wherever it is rooted in the heart. (1:5.9)
"The righteous...still bear fruit in old age, they are ever full of sap and green, to declare that the Lord is upright; he is my rock, and there is no unrighteousness in him." (Ps 92:12-15)
He is to be known so that He may be adored, not just minutely discussed.
