By making the Apostle Paul weak, God showed His own power and strength.
That sounds like a paradox but it’s true. God gets far more glory out of weaker Christians as they lean on Him.
1 Corinthians 1:27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;
The disciples were ordinary weak men, but God used them to alter the world for His glory.
When the Lord allows trials and sufferings in your life, He has a plan and He’s getting glory out of your weakness.
You may never know this side of eternity just how He used your pain.
But someone is watching or God is working through it some way for His glory.
