What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[GrandizerII]

It might be thought … that evolutionary arguments would play a large part in guiding biological research, but this is far from the case. It is difficult enough to study what is happening now. To figure out exactly what happened in evolution is even more difficult. Thus evolutionary achievements can be used as hints to suggest possible lines of research, but it is highly dangerous to trust them too much. It is all too easy to make mistaken inferences unless the process involved is already very well understood. 

— Francis Crick

And the Bible says "There is no God"!

What's the context of the quote? It's not like context doesn't matter, dude. But you know what, even just reading this one quote is clear that he wasn't debating the concept of evolution itself. So perhaps you should reread the quote you pasted, or at least provide some damn context next time.

Happenstance is just another word meaning abiogenesis. The whole premise behind abiogenesis is happenstance.

Depends on what you mean by "happenstance". Abiogenesis could be gradual, not sudden.

The hypothesis is that conditions were just right for life to come about by extraordinary means.

What extraordinary means are you talking about? You're the one positing supernatural causes here.

However due to the amazing complexity of the DNA molecule, abiogenesis is an impossibility just like it is an impossibility for nature to create a encyclopedia when there is a windstorm with lightening.

That's not how scientists think abiogenesis happened on this planet. It's not like life suddenly was switched on just like that. You know the line between "non-life" and "life" is fuzzy and arbitrary, right? And we're not arguing life is a supernatural soul. It's an abstract that describes some mechanism that gradually emerged from molecules and such via very natural processes. And it started out as something really basic, way more basic than an encyclopedia. So your analogy is false.

I don't think you really understand just how improbable abiogenesis is.

I don't think you really understand the distinction between impossible and improbable. If something is improbable, then it still can be possible (so long as the probability isn't exactly 0). It's improbable that you would win the lottery prize, but it doesn't mean it's impossible. You might get lucky and actually win, not just once, but two or even three times during your lifetime.

He didn't argue that things create themselves. The argument is that chemistry is a thing ... that happens ... naturally, without the need for divine intervention.

So God can't create something which works by itself?
An automatic gearbox doesn't cancel the inventor does it?

What's the point of positing God if things can work by themselves anyway? Learn to use some Occam's razor when you get the chance.

Life and automatic gearbox are two different things.
