If you don't reject metaphysics and you understand hypotheticals, then my hypothetical argument from Providence should not be problematic for you in any way.
As to your many-ideas-of-God cavil, I refer you again to my charming little thread in the Theology forum entitled "50 Million Frenchmen Can't Be Wrong," and while I appreciate the level of difficulty involved for the skeptical imagination to come to terms with its own limitations and to grasp the primary truth of theism along with the deficiency of atheism -- to understand, that is to say, that the question of faith is not multiple-choice, except in the mind of the faithless, that the multiple-choice concept of God is merely the invention of agnostic or atheist or scientific attempts to reduce to manageable terms that which is essentially beyond its ken. In other words, my argument is logical, not doctrinal. If -- and you say you understand hypotheticals, so this "if" should signal hypotheticality to you in no uncertain terms -- if God (Divinity, Transcendent Spirit, Ultimate Reality) intervenes in the world, then God (Divinity, Transcendent Spirit, Ultimate Reality) intervenes in the world. That is my argument in a nutshell, and any and all objections to this virtual tautology spring from agnostic or atheistic or skeptical or scientific deficiencies in understanding the discursive space in which this argument unfolds.
