“Each time he said, “My grace is all you need. My power works best in weakness.” So now I am glad to boast about my weaknesses, so that the power of Christ can work through me.”2 Corinthians 12:9 NLT
Although God did not remove Paul’s affliction, he promised to demonstrate his power in Paul. When you are weak God is able to display his power in you. This should give you courage and hope. It’s okay to recognize your limitations then you will depend on God for your effectiveness rather than on your own energy,effort or talent.
