If we cannot identify ourselves as wilderness people, we will have a hard time understanding the context of Advent. The advent of Christ is to bring good news to the poor, release captives from slavery to sin and death. If we can’t claim our own wilderness, perhaps we should align ourselves with those in the wilderness.
Too often we play a guessing game with Christ’s identity, in which we force our perceptions and our desires of a Messiah upon Christ. But Christ didn’t come just for you, Christ came for all people, so stop claiming an infallible opinion of the Messiah, or you’ll be rebuked, just like Peter.
For the Biblical text to truly be helpful in our understanding of salvation and the saving work of God, it requires us to have an understanding of the text that goes deeper than what a simple surface level reading can provide. Isaiah 55 is a good example.
