God is sovereign and we are not. All things are from Him, through Him, and to Him, as Paul says in Romans 11:36. Therefore, everything that He does is for the sake of revealing Himself and His glory. It is a great honor, therefore, to be used of God for this purpose, for His glory is the most wonderful thing of all. That we are instruments for revealing this glory is a great privilege, and it will make all of our suffering worth it in the end.
