Yesterday I remembered a time in prayer when I was honest about not feeling fervent, and God welcomed my honesty. I remembered last night a thought from Psalm 25. The first verse says (in some but not all translations) "To you, O LORD, I lift up my soul."
Yes, to the Lord, I lift up my soul. My soul as it is, not the soul I should have, not the soul I'd like to think I have or want others to think I have. But the one I really do have, with its warts and imperfections, ego, selfishness and pride. That is the soul I've got, that is the soul God has resolved to transform. He knows how much is yet to be transformed, and does not view finishing the task as impossible or even arduous.
