Whenever I think of affirmation, Al Frankin as Stuart Smalley comes to mind: I'm not a big fan of self-affirmation. At least not when God is left out of the equation. To me, trying to empower yourself without acknowledging where that power comes from just walks too fine a line with sinful pride. My affirmation comes through faith and prayer. Be it to invoke the power of God or to invoke the power God bestows upon us in his name. So when I say, I just can't do this... or this is too hard... it's not negative at all. I'm simply acknowledging my limitations without God.
