"God [..] it would be trivial for Him to raise Himself from the dead"

It would. But maybe he is crying for humanity as we slowly start yet another religion, costing us yet another two centuries to recover from. Why would a god even need a sacrifice? A very human notion I think.

"although this is generally covered in the Old Testament as well"

Jesus said pretty much the same thing, he says the golden rule is what the law of moses comes down to. But you don't have to look far to see that that is a bit too generous. I mean, stoning a woman if she is not a virgin at her wedding night? Stoning homosexuals? Allowing slaves? There is some horrible bronze age thinking codified in the old testament. Not to speak of the genocide and promise of more genocide in the future when Israel will rule and drink the blood of its enemies.

"The Holy Spirit is a person"

I would like to meet that person. Or watch him/her give a presentation on youtube. But I suppose you mean he is not flesh and blood, so not an actual person. Around 1900 there were many claiming to have an (heavier than air) airplane. You proof that by inviting the media and flying one. Not by handwaving or reasoning.

"Jesus died for our sins, and He gives us power to live new lives in freedom."

How? I mean that literally. How does he deliver you from sin? You mean here on earth? Or only in heaven? If it has an impact here on earth, then isn't that just an idea that delivers you from sin? The idea that you can be forgiven, and that others will forgive you? Just because we sin sometimes, doesn't make us sinners. If that were true, than doing good sometimes would make us all saints. It is a mix of both at the same time. And we can be forgiven, by others and by ourselves. Start over, learn, try to do better.

"Without meaning and significance life is a cruel joke!"

I understand the sentiment. But it is not about the destination, it is about the journey, it is about who you meet, what you learn, what you teach. We are connected to so many people, and in our connectedness, we are more then the sum of our individuality.

Some people are born in poverty, suffer for lack of food and health, and maybe abusive people around them. Their lives are short and brutal, like so many lives in the past. Will there be some cosmic justice? It is a nice idea but it is unlikely. The only faint flicker of hope is that they have ceased to exist, that their suffering is now over.

We should take their lives to heart, make sure it happens the least amount of times possible. By living the way Jesus told us, not because something supernatural exists, not because then you go to heaven, but because that ends cruel joke of life, and turns it into something worth living.

As to Pascals wager, he was a mathematician, and the chance is good he is spending eternity in hell. Around 2 against 1. Just not the christian hell, but the hell of any of the other religions.

Or maybe he is now in heaven, but it is hell to him, because by believing he signed his life away in the service of god and his army. And god is indeed this cruel dictator, the North Korea of the heavenly realms. An ending that fits the old testament much better ... a cruel joke indeed.

And that brings us full circle. How can you know the difference between bronze age thinking, dictatorial propaganda, or a loving god?
