The quality of human life is not a valid measure of the value of human live. It is not a valid statement that only a certain kind of life is worth living. The feeble, impaired, or hurting should be able to die if they, or I, want. All men are created in the image of God and are therefore bearers of the image of God. Bearing the sacred image of God makes human life sacred.
All innocent men deserve life.
All men should choose life for themselves and others. Armed with these three biblical principles. But, I do not choose, however to remain on a respirator indefinitely in an unconscious state of mind. If I should survive the cessation of respirator therapy for twenty-four hours, I choose to be resuscitated again if I should stop breathing or my heart should stop beating. If death is apparently immanent, then I want to receive sufficient pain therapy to make me comfortable even if it might compromise my survival.
