12:9 And he hath said unto me, My grace is sufficient for thee: for `my' power is made perfect in weakness. Most gladly therefore will I rather glory in my weaknesses, that the power of Christ may rest upon me.

1:6 being confident of this very thing, that he who began a good work in you will perfect it until the day of Jesus Christ:

1:9 Have not I commanded thee? Be strong and of good courage; be not affrighted, neither be thou dismayed: for Jehovah thy God is with thee whithersoever thou goest.
