I loved this popping up in my FB newsfeed, it obviously reminded me of the Bible verse (also below) and I think its true. I believe that when we arm ourselves with our weakness, the devil flees, because God is then taking over where we leave off. Its by His grace alone.
2 Corinthians 12:9-11New King James Version (NKJV)
9 And He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. 10 Therefore I take pleasure in infirmities, in reproaches, in needs, in persecutions, in distresses, for Christ’s sake. For when I am weak, then I am strong.
