Evidence based theology?

As a thought experiment, let's assume we know nothing of what a deity is, and then try to derive some properties. I feel, along with many other intelligent people, that there is a way to be spiritual and yet be consistent with logic and reason, so this could be a worthwhile experiment. One of the first difficulties we encounter is that there is no good definition of "God." If one goes the simplistic route and defines God to be an omnipotent being, one gets into trouble since omnipotence is a logically inconsistent concept. (If God can do anything, he can make a rock so heavy he can't lift it.) Notice how I used "he" to describe God. This shows a lot of preconceptions that people have: that God is an intentional agent, and moreover, can be assigned a human gender! In any event, this simple argument shows that God, should one exist, is not all-powerful in the most simplistic sense. Indeed, if that were the case, he would snap his fingers and dissolve the suffering of the world in an instant. But the force of God evidently cannot instantaneously dissolve the suffering of the world. (I don't believe there is a difference here between "cannot" and "doesn't choose to." Aside from the problem of assigning intention to an unknown quantity, there is also the conundrum of whether one can ever choose to do act in a way differently than one actually acts. ) This solves a lot of the questions people have, and the reasons that are frequently given about why faith is not an option. But notice that it does not prove or even, to my current way of thinking, make a dent in the possibility of a spiritual force that can dissolve suffering, just not instantaneously. In fact, I believe that one need to be open to help from a spiritual force, in order to receive help, at least efficiently. We are more powerful than that spiritual force, in a gross sense, because we can choose to ignore it. It cannot control us like automatons. Yet, in a subtle sense, we are not more powerful than it, and in fact, I believe it is our innermost nature.
