It is not about becoming spiritual beings nearly as much as about becoming human beings. The biblical revelation is saying that we are already spiritual beings; we just don’t know it yet. The Bible tries to let you in on the secret, by revealing God in the ordinary. That’s why so much of the text seems so mundane, practical, specific and, frankly, unspiritual!
We have created a terrible kind of dualism between the spiritual and the so-called non-spiritual. This dualism precisely is what Jesus came to reveal as a lie. The principle of Incarnation proclaims that matter and spirit have never been separate. Jesus came to tell us that these two seemingly different worlds are and always have been one. We just couldn’t see it until God put them together in his one body (see Ephesians 2:11-20).
