My God is infinitely greater (and exquisitely more subtle) than the one described in the Bible. My God created a universe perfect from the instant of creation for His inscrutable purposes, with no need for seams or thumbprints or incessant interference to keep it on the correct path. The God described in the Bible was unable to do that. Why?
Because there is more to life than math and physics. God was not unable, He was unwilling.
Now there you go again, posting something interesting. Where, Physicist, is your God? "Out there", disinterested, watching? Is it possible for your God not to be a part of His Creation and, if so, how so; i.e. what did your God have to work with? Can such thinking be classified as anything more than a fundamental assumption, always acknowledging that such assumptions are indeed important?
Well, first of all, Physicist, the universe has an awful lot of stuff that looks less than perfect (broken electro-weak symmetries, as an example). But as to people, most religious people believe that God gave people free will. Along with the free will came the possibility of doing bad things, of evil. The whole point of God's intercessions, for Christians (and in particular, sending us Christ), is to help people get back on track, and to convince, cajole and push them to reject evil and to embrace goodness. (As per the Lord's prayer... "and lead us not into temptation, but deliver us from evil...)
