Hmmm. So the weaponization of gun powder turned Christianity into a world power. I think Christianity was a world power long before that.
That depends on what you mean by "world power". Certainly Christianity was largely contained within Europe before the weaponisation of gunpowder, and despite several attempts to invade and subdue their Islamic neighbours, they generally came off second best - to the point where the far more civilised Islamic powers controlled most of the Iberian peninsula, and were able to repeatedly drive the Christians out of the Middle East.
It really did require a revolution in military technology, and technology in general, before the tables were turned.
Bizarrely, this was due to the Muslims (correctly) anticipating that scientific study of reality would move people further from religious belief, and as a consequence inhibiting its pursuit to the detriment of their military capabilities; While the Christians (incorrectly) anticipated that scientific study of reality would provide further evidence that Christianity was correct in its tenets, and so they encouraged the R&D that led both to military success, and to increasing secularisation.
So now the so-called "Christian" world is Christian in name only - most citizens of Western Europe are "cultural christians" who might go to church for weddings and funerals, but who otherwise give no thought whatsoever to religious belief. They typically still tick the 'Christian' box on censuses and surveys, but certainly none of the participants in the Early Modern religious wars would consider these modern descendants to be Christians.
Today we see an Islamic world that has the passion and the faith, but not the technology to take over the world; And a Christian world that has the technology, but not the passion or the faith to bother to use it to attempt to crush their religious opponents. Iran is a theocracy, and wants to eliminate America for religious reasons, but hasn't got the weapons or delivery systems to do so; America (and Russia, and China, and France, and the UK) have both the weapons and the delivery systems to eliminate any nation on Earth, but these countries are largely secular, and so have no desire to do so (or at least, no desire to do so to any nation without the military strength to deter them from doing so), so far.
I am pretty sure that if you think Christianity was a world power before the weaponisation of gunpowder, then you are (yet again) thinking something that is simply untrue, but that you believe because it supports your prejudices, and so you have never bothered to question it.
Given your evident lack of knowledge of history, I am astonished that you expect anyone else to care one whit what you think.
