Everything ranging from what can be inferred in the historical sense from the gospels regarding the resurrection to the testimony of Church fathers (who lived inside of living memory of the event) and extra biblical sources that speak of the history at that time.
So, I’m gauging that you have total faith in the historical value of Gospel, which has several historical inaccuracies. This is fine, as long as you are aware that the writers had the sustainablility of the Christian religion as a foremost priority, amongst a savage community of Jews and Gentiles, who leveraged large chunks of their belief systems on superstitions and myths, the more astounding and awe-inspiring, the better.
One has to also question why the station of John the Baptist is systematically downplayed as we read from the 1st to the 4th Gospel.
Secondly, by what basis do you trust the testimonies of the Church Fathers, many of whom never met Christ?
Thirdly, what extra-biblical sources are you referring to that provide verifiable history in relation to Jesus’ life?
The point here is not why I should be Christian. The point here is whether or not you can see that this is the reasonable way to determine whether to reject or accept a religion. Without answering that, you seem to want to discuss Christianity.
I see it as a reasonable way if it had just one non-Christian verification. Outside of Christian texts there is nothing about Jesus’ miracles and physical resurrection, nor of the several saints who were resurrected at the same time as Jesus’ resurrection. You’d think the Romans who were remarkably good record keepers would at least mention, just once, the fact that all these dead bodies had been resurrected?
Outside of any verification, I see your justification for the Divinity of Jesus as very theologically thin, and lacking depth. Jesus’ religion was so so so much more than any supernatural feats which were only witnessed by those who believed.
Is there no other analysis that can provide faith in Jesus?
Did Jesus say “those who believe in my miracles are my mothers, and brothers and sisters…”??
No, He said, “those who do the Will of God are my mother, and brother and sister…”
there is serious chasms in theological richness between the true statement and the one I made up for comparison…
