I stretch out my hands to You; my soul thirsts for You like a parched land. Selah
The second verse of a song you've sung for years is a strange place to discover you feel nothing, but that is often where it shows up. Prayer can go the same way, with the words still said before meals and at night but seeming to land on the floor. A Bible that once got underlined can end up on the bedside table looking like homework.
