Sometimes prayer doesn't always change "things" the way we expect...Sometimes we are the ones transformed/transfigured as we pray.
Paul was given grace and strengthened to endure the thorn in his flesh. THE KEY TO THE TRANSFORMATION OF US OR THE SITUATION IS TO PRAY! God's answers according to His will, wisdom and sovereignty.
As He prayed, the appearance of His face was altered, and His robe became white and glistening.
Luke 9:29 NKJV
