forget not His benefits

John Piper, and now Jonathan Edwards and a slew of Puritans. Topic: meditation. My status: generally failure. Repentance and prayer. Generally more failure.
John Piper preached,

Suppose you are feeling unworthy and unacceptable to God and generally a failure and having little motivation to rise above the sense of despondency. Now, you have lots of knowledge in your head of Christ's great deeds of old. And if someone says to you, "But don't you know that you are justified by faith and God looks on you in Christ as you cast yourself on him for mercy?" you might say, "Yes, I know that in my head, but it isn't having any effect on my feelings."

Indeed. And then Piper tears that idea down as lazy and passive and demonstrates what true "head knowledge" of the Gospel is and does. I've felt intimidated, not really sure where to begin, as if I were dipping my toe into a deep, deep sea.

Last week at work, this kept popping into my head: "Bless the LORD, O my soul, and forget not His benefits." I wrote it all over the place, on my write-off sheet, on the dry-erase boards, on the hoagie paper, napkins, receipts, everything. I couldn't get the phrase out of my head.

So last night I went and found the Psalm it comes from--One Hundred Three. I don't know that I have ever been so encouraged in all my life of God's presence and work in my life.
