Bless the Lord, O my soul, and forget not all His benefits; (vv. 1-2) Can't you just see David pacing the room, declaring these words to his own soul. Almost taking his soul by the chin, so to speak, and pointing it upward to God Most High. "Bless the Lord!" he instructs, "Forget not His benefits!"
The truth is that there are days we are not going to "feel" the stirring of God in our soul's. And it is not because God has moved or changed. It is us. We are the ones who get distracted. We are the ones who wake up with lists trailing in our minds before our feet hit the floor. We are the ones who focus in on the temporal things of this life, when only the eternal truly satisfy. We have to make the choice to set our minds on that which gives life; meditate on things that are true, noble, just, pure, lovely, and praiseworthy (Philippians 4:8).
So give your soul a good preachin', and forget not all His benefits: He forgives, heals, redeems, crowns you with lovingkindness and tender mercies, and satisfies your mouth with good things so that your youth is renewed like the eagle's. (vv. 3-5)
