LC is so proud of their "last Adam became a life-giving Spirit" revelation. It is like one of the main stones for their theology. A simple question remains though: does it really matter? We can cut and paste lots of verses and arguments, but the bottom line is whether knowing that Jesus is a Spirit changes my life significantly or it is just a cute teaching that makes me feel special?
Another thing is that all our concepts about God are at best pointers to the Truth, but not the Truth itself. When we really stick to a concept, we are that proverbial fool who looks at the finger, not at the Moon.
