2 Corinthians 12:9-11

9 But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.”Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. 10 That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.

21 days of prayer and fasting maybe made some of us feel physically or mentally weak. The encouragement that Paul gives is when we are weak, then we are strong. Our weakness is an invitation to depend on the strength of God versus the strength of self, which empowers us to withstand the attacks of the enemy. 

Let’s keep leaning on His strength!
