So you admit that you are merely assuming that these men were messengers of god, based on what those men said. There is always the possibility that they were either delusional or dishonest - even if you don't believe they were.
Are you claiming that anyone who willingly suffers persecution for their cause is necessarily a messenger of god?
So what? How does that show they were talking to god?
So you
are saying that anyone promoting a new ideology who is persecuted is a messenger of god?
No they didn't!
Hitler, Stalin, Mao, etc all managed pretty well.
Are you seriously claiming that Christianity and Islam became global without the use of force and without any financial backing?
Not a fan of history then?
More claims without evidence.
And meaningless platitudes.
This is the thing. God can do literally anything. If he wanted to appear to everyone in the world, without using human intermediaries, in a way that we all found convincing and appealing - he could. In fact, he
would. The very idea that god deliberately makes it so that the majority of people will reject him is utterly incoherent.
