Doesn't the bible say you should live by faith?
There are many historical evidences in Christianity, but there are in other religions too. I'm pretty sure no Christian Denies the Existence of Buddha, a precedent teaching of Hinduism.
The only reason I say there is no way to know for sure, is well, honestly we don't we know after we die 100%. Any Christian who says they 1re 100% sure is only lying to them self. Because other faiths even some off branches of Christianity like the LDS and Jehovah's witnesses say they are 100% certain. NOT everyone can be 100% certain. Even Mathematically there is some error. involved. Let's say Christianity isn't the right way you waste your entire life, and may go to some other faiths hell, or purgatory. What about the Chinese in 1000 BC? is it fair they go to hell? The way Christianity has it self set up is Jewish people and middle eastern get saved, along with some modern western people.
All I am saying is God should be a just God and take all of this into account, and I just don't buy the "you have to do x,y,z" in Christianity. We have all fallen short and sinned every Generation, why is it only a select time period get saved?
Let's say I am wrong and I face God and he knows that I have Confessed a sinner, but some native American from 1200 AD goes to hell? I don't know
