"And to whom shall I confess my ignorance more profitably than to you, for you do not look with distaste at my violent burning enthusiasm for your Scriptures? Grant me what I love...This is my hope for this I live, that I may contemplate the delights of the Lord." --Augustine, Confessions, XI.22.Even I my best days, I fear I cannot hold a thimble to this passion.
“I want to so thoroughly master God’s Word so that I might be mastered by it. It is in the true mastery of God’s Word that my Triune God will in turn master me. Mastery of God’s Word is nothing more than an act of humble submission to it in all things. We submit to it because we submit to the authority and the supremacy of the One who has spoken forth this life-giving, soul- splitting, sin mortifying Word.”
Here is where I need to keep my sin in check in one of two directions: (1) Laziness, plain and simply laziness is the biggest threat to truly mastering God's Word and engrossing oneself in study. (2) Mastery of the word for merely intellectual purposes. This sort of seeking of knowledge certainly does puff us up. Our mastery of the Word should be a humble act, not so that we 'lord it over the text' but that we submit to what the Word actually says.
Piper's last line is just classic: "Oh my there is just a lot of foolishness going on."
