I disagree; no religions speak about a God who assumes tha human nature and accepts to suffer and die in order to save us.
That's not what I said. I referred to the concept of "God and divine love," which is not unique to Christianity.
I am not sure to understand your question, but I try to unswer.
As I have explained, it is the christin concept itself of divine love that makes me believe that God of the christian faith is the true God.
A concept is just a concept. Everyone has them.; all sorts of them. That doesn't make them true.
An idea isn't evidence. People have ideas about Santa Clause, faeries and Vishnu, but this isn't evidence they're real.
And again, why do you believe the concept of divine love is exclusively a Christian concept?
I am a physicist and I think that a rational analysis of our scientific knowledges provides a strong and convincent argument supporting the existence of a personal intelligent God. In fact, all what science shows about the universe is that it manifests itself to us as a realization of some specific abstract mathematical models (what we call “the laws of physics”); in fact, the subatomic components of matters (quantum particles and fields) are actually only abtract mathematical concepts.
I'm not seeing this "strong and convincing" argument. Your conclusion seems to be your premise.
What concrete observations are you starting with, and what steps lead you to this god conclusion? Is it testable,or predictive? Can you explain?
On the other hand, mathematical models are only constructions of the rational thought and a mathematical model can exist only as a thought in a thinking mind conceiving it; therefore the existence of this mathematically structured universe implies the existence of an intelligent God, conceiving if as a mathematrical model. In other words, the universe can be only the manifestation of a mathematical theory existing in the mind of an intelligent and conscious God, i.e. a personal God.
I see no such implication. The universe and the laws are what they are. The laws are testable, predictive, and give repeatable results. I see neither evidence not need for an intelligent or purposeful God, the impersonal, undirected laws work quite well without capricious interventions.
This "argument" doesn't follow.
Once you understand that God is the Creator of the whole unverse and of ourselves, you can understand that God is certainly superior to ourselves. Since God has the capacity to create our intelligence, our consciousness and our will, He must be intelligent, conscious and He must have a will.
I have to believe in your conclusion before I can understand it? This doesn't follow, nor does this
a priori "understanding" give us any reason to believe in an unnecessary, unevidenced mythology.
In fact, since God is superior to us and He is the Creator of our own capacities, He must possess our own capacities in a superior way. Since God is superior to us, He must have a superior capacity to love.
Once you understand that the Creator of the universe must be a loving God, you may understand what I wrote in my first about the reason why I believe that the God of christian faith is only true God.
Again, you're putting the cart before the horse, so to speak; arguing backward from your conclusion. This is just preaching.
