At the beginning of his work, Jesus went into the wilderness for forty days (Luke 4:1-13). There, in the desert, he met the devil, or, his demons—so to speak. There, he had to confront the most formidable challenges to his faith, his vocation, and his relationship with God.
Through that experience, however, Jesus affirmed his true calling. That is why, I suspect, the church has always valued connecting with the wilderness as an important aspect of the faith journey.
We are called into the wilderness—into nature—to listen, to prepare, to be tested and to be encouraged. In the end, as Jesus was, it is in these wilderness experiences where we are strengthened by grace.
