So also is "flimsy evidence" a subjective comment. To me, it is not flimsy at all. And to answer your post, yes I agree, he could just reach down and save us from that cliff. However, we still retain the Right to choose to accept that hand and God will honour that wish instead of forcibly grabbing us and pulling us up (arguments of predestination aside, which is a topic worthy of its own thread).
That reminds me of something Christ says in the Bible. He says that he is standing at your door waiting to be invited in.
