First, let me apologize to Brant for any inference that he represents the opposite of my views. My discussion of the Schaivo issue has been broad, both on blogs, in comments, and in personal conversations. But online, Brant is the only one I've referenced. My characterization of certain views should not be directly linked to Brant's views. Brant has been very willing to allow me to engage the conversation.
Second, it is a tremendous reminder of how difficult it is to communicate in writing and a reminder that I am an amateur and apologize as well for statements that are not well thought through and are offensive in ways that I hadn't imagined.
Now for an argument for life.
As I've studied Abraham lately (the patriarch of Judaism, Islam, and Christianity found in the middle chapters of the book of Genesis), I discovered that the Gospel is in many ways the very offer of life and that faith is the willingness to release control over our situations. As applied to Schaivo, it may very well be a question of trusting God with the life that He has given. It is the ultimate release of control. The fear of having that much loss of control may be at the very heart (or nearly so) of the nature of sin.
The engaging question: Does life come anywhere but from God? Even with loss of control, should we leave the issue of life in God's hands?
The question would have to be engaged at a personal level where we can mostly agree and that probed at the extreme.
