Uh, being 'weakness, as part of not having confidence in your own strength" somehow seems a bit 'trite' to me. I do not know anyone alive who begs for nor demands weakness in any format, to be heaped upon themselves so that they can become stronger, spiritually speaking. Yes, we pray, once we have contracted a disease or condition, so that we can be healed or make it through, but nobody asks for it ahead of time in order to become stronger.
