In The Wonderful Wizard of Oz, Dorothy, the Scarecrow, the Tin Man, and the Cowardly Lion return to Oz with the broomstick that empowered the Wicked Witch of the West. The Wizard had promised, in return for the broomstick, that he would give the four friends their deepest desires: a ride home for Dorothy, a brain for the Scarecrow, a heart for the Tin Man, and courage for the Cowardly Lion. But the Wizard stalls and tells them to come back the next day.
While they plead with the Wizard not to send them away, Dorothy’s dog Toto pulls back the curtain, behind which the Wizard spoke, to reveal that the Wizard isn’t a wizard at all, He’s just a fearful, fidgety man from Nebraska.
It is said that the author, L. Frank Baum, had a serious problem with God, so he wanted to send the message that only we have the power to solve our problems.
The apostle John in contrast pulls back the veil to reveal the truly Wonderful One behind the “curtain.” Words fail John (note the repeated use of the preposition like in the passage), but the point is well made: God is seated on His throne, surrounded by a sea of glass (Revelation 4:2, 6). Despite the troubles that plague us here on earth (Revelation 2–3), God is not pacing the floor and biting His nails. He is actively at work for our good, so we can experience His peace.
