From Desiring God Blog:
Practically, this gets down to the details of how we approach Scripture. In chapter nine of When I Don’t Desire God, John Piper introduces a helpful acronym of how to pray over our Bible reading. This acronym — I.O.U.S. — is taken straight from the Psalms and anchors our aim in reading by four explosive verbs: incline, open, unite, satisfy. I still have this prayer taped to my desk on the yellowed index card on which I first copied it. I have petitioned God for this work virtually everyday for the past decade.
Incline my heart to you, not to prideful gain or any false motive.
Open my eyes to behold wonderful things in your Word.
Unite my heart to fear your name.
Satisfy me with your steadfast love.
