I did read the whole article, and if you'll forgive me for oversimplification, what I got out of the article is (1) do no harm; (2) be thankful for what you have.
I don't know if this is really 'deism' though. It seems to be a deistic tangent on Christianity. (Edited to add: Duh. I re-read the title of this thread. Helps if one pays attention before shooting off!).
I always thought of deism as something along these lines:
Deism is a religious and philosophical belief that a supreme being created the universe, and that this (and religious truth in general) can be determined using reason and observation of the natural world alone, without a need for either faith or organized religion. Deists tend to reject the notion of divine interventions in human affairs – such as by miracles and revelations, but not necessarily. These views contrast with a dependence on revelations, miracles, and faith found in many Judeo-Christian, Islamic and other theistic teachings.
Deists typically reject most supernatural events (prophecy, miracles) and tend to assert that God (or "The Supreme Architect") has a plan for the universe that is not altered either by God intervening in the affairs of human life or by suspending the natural laws of the universe. What organized religions see as divine revelation and holy books, most deists see as interpretations made by other humans, rather than as authoritative sources.
