Our belief or disbelief in God adds nothing to nor takes anything away from His glory, any more than our sight or hearing commands the sun and the birds. But if we were suddenly struck by disobedience and self-conceit to steal God's glory, even then He would remain undiminished. God's glory is His and His alone, and with no other does He share it.
How tempting it is to claim the credit ourselves for the mighty works God does in and around us. Perhaps no one feels that temptation more than those who serve God in a public ministry—those who have been called to hold His glory in sacred trust. Whether their work becomes a movement of God or calcifies into a monument to themselves depends on one crucial factor: who gets the glory.
