When I am finally being brought to the conclusion that I know nothing, understand nothing, can accomplish nothing, am nothing. As I begin to see more and more my own failure and weakness and sinfulness....
"And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong." (2 Corinthians 12:9, 10 KJV)
