His grace is sufficient, His power is perfected in our weakness

Scripture reference

2 Corinthians 12:9 (ASV)

9And 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.
