⁷ Two things I ask of you;
deny them not to me before I die:
⁸ Remove far from me falsehood and lying;
give me neither poverty nor riches;
feed me with the food that is needful for me,
⁹ lest I be full and deny you
and say, "Who is the Lord?"
or lest I be poor and steal
and profane the name of my God.

Ian meditates on (1) the prayer, (2) the warning, (3) the instruction, and (4) the promise of the passage.  The sermon is a model for clarity, plainness of speech, preaching Christ from the content and themes of the passage, demonstrating the unity of the Scripture, humility, being personable, and application. At 37 minutes, the brother is efficient, too!  But most importantly, the word of God was searching my heart and life with regard to my prayers, my contentment, and whether my relationship with Him is constantly the greatest thing to me.  Ah, what help for my soul!

Now that I've recommended it to you, I'm going back to ponder Proverbs 30:7-9 some more.  If after you've listened you'd like to think more about this, you might consider Craig Blomberg's excellent book, Give Me Neither Poverty Nor Riches: A Biblical Theology of Possessions.
