Let's pretend God's plan for my life was to go through a trial of endless suffering where, it appears by all means I was utterly forsaken and victim of global conspiracy. But after so long I decried the Lord, rather than accept persecution being innocent, then should I still believe the Lord wouldn't have put me through that except I were chosen and it was for my perfection therefore I am yet secure.
I failed a difficult yet worthy challenge and failed extremely valuable opportunity when I knew faith was always the only answer no matter what. Failure bing the key word here. So failure is the end thereof and of me. So I can forget about confidence altogether.
