In Revelation 22, John is so overwhelmed by the angel who is showing him the visions that he falls down to worship the angel (22:8).
The angel quickly corrects John’s wrongly directed worship:
but he said to me, “You must not do that! I am a fellow servant with you and your brothers the prophets, and with those who keep the words of this book. (22:9)
And then in two words, in the very last chapter of the Bible, the angel summarizes what I think is the call, the invitation, the command of the entire Bible.
All that happens in the drama of redemption, in the scope of biblical and human history, is directed towards this ultimate goal: “Worship God.” Everybody worships something; it is all important, a matter of life and death, the difference between heaven and hell, that you worship God.
