I want to be what this message is about. This is "Think Hard, Stay Humble" by Francis Chan at the Desiring God Conference. Here's the text it's based on.
1 Corinthians 8:1-3 (ESV) - Food Offered to Idols
1 Now concerning food offered to idols: we know that "all of us possess knowledge." This "knowledge" puffs up, but love builds up. 2 If anyone imagines that he knows something, he does not yet know as he ought to know. 3 But if anyone loves God, he is known by God.
