Jesus’ actual existence as a real person is basically a historical fact.
But I find it completely irrelevant for convincing anyone to become a Christian. Even if Jesus somehow actually rose from the dead, it’s still not particularly relevant.
Because power has no relevance to morality. Jesus can die and resurrect as many times as he wants, but as long as his teachings make zero sense from a moral perspective, it makes no difference.
But if the teachings make sense, then it doesn’t matter whether Jesus even existed. He could as well be a mass-murdering serial rapist, and it would not take away one bit from the wisdom of his moral teachings.
As far as I can tell, Christianity is really supposed to be about whether or not Jesus’ teachings make sense morally, and whether people want to live their lives accordingly.
Interestingly, the bible articulates this very principle:
Luke 16:27-31 Common English Bible (CEB)
27 “The rich man said, ‘Then I beg you, Father, send Lazarus to my father’s house. 28 I have five brothers. He needs to warn them so that they don’t come to this place of agony.’ 29 Abraham replied, ‘They have Moses and the Prophets. They must listen to them.’ 30 The rich man said, ‘No, Father Abraham! But if someone from the dead goes to them, they will change their hearts and lives.’ 31 Abraham said, ‘If they don’t listen to Moses and the Prophets, then neither will they be persuaded if someone rises from the dead.’”
That’s why, while I consider myself as a sort of “Christian”, I think most people who call themselves “Christian” are completely missing the point. Most of the world, Christian and Atheist alike, have been sold this bullshit idea about worshipping some god whose existence is completely uncertain, in order to escape some fictitious hell that is not even explicitly mentioned in the bible.
People (especially “Christians”) who are worried about whether God really exists, whether Jesus really rose from the dead, etc., are just sycophants who are not actually interested in the moral teachings, and are just worried that their sycophancy will go unrewarded. Well, good luck with that, because apparently God cannot be deceived.
Matthew 7:21-23 Common English Bible (CEB)
21 “Not everybody who says to me, ‘Lord, Lord,’ will get into the kingdom of heaven. Only those who do the will of my Father who is in heaven will enter. 22 On the Judgment Day, many people will say to me, ‘Lord, Lord, didn’t we prophesy in your name and expel demons in your name and do lots of miracles in your name?’ 23 Then I’ll tell them, ‘I’ve never known you. Get away from me, you people who do wrong.’
