As a follow-up to what you're saying:
Was Jesus a real person existed, likely.
Agreed
Did he rise from the dead, no.
Disagree. If (and notice I'm using the 'if' proposition) there is a God, who created everything, it would be trivial for Him to raise Himself from the dead. Like I mentioned before, if Jesus did not rise from the dead, then Christianity is moot and should not be followed. This is the singular point in human history that has a binary answer with eternal implications.
Was his message misunderstood, yes.
Agreed. In fact there are many other christs and gospels (2 Corinthians 11:4). No one counterfeits worthless things, but if (there's that 'if' proposition again) Jesus is who He claimed to be, then what He offers is the most valuable thing in all of human history: Eternal life. Immortality. To be in God's Family and be owners of _everything_, not just all the stuff on earth, but everything in the universe.
Part of Jesus his message was, it is not about what you do, but why you do it. It is about your heart.
Agreed. Amen.
An eternity in heaven or hell are exactly the wrong motivation.
Food for thought. I'll need to chew on this one for a bit.
I think Jesus meant humanity can go much further if we all follow the golden rule,
and are less biased towards foreigners and outcasts. More grace more forgiveness,
less judgement. When two or more people cooperate in that way, they can do more.
Agreed, although this is generally covered in the Old Testament as well. The problem is not should people get along, but the problem is _why_ people don't get along. The Bible calls this thing 'sin'. We all sin. The proof is in the fact that even if you are not a Christian, we all have things we believe to be right and wrong. And yet, we still choose to do things that we know are wrong! Jesus died for our sins, and He gives us power to live new lives in freedom.
That is the holy spirit, not some supernatural force.
Disagree. The Holy Spirit is a person, just as Jesus is a person and the Father are a person. Three persons, one God. Do I understand that? No. Can I apprehend it? Yes.
And that will bring the "kingdom of heaven" here on earth.
It might not feel like it, but we are getting closer to that.
How many lepers did god heal? 50 total? Science has healed 5 million.
You forget one glaring fact: 100% of those lepers 'healed' by science all die. In fact at some point, all human life will die. Then what? What's the point?
Just keep asking yourself that question "then what". You are born. Then what? You go to school. Then what? You get a job Then what? You (get married | stay single | become successful | etc) Then what? You get old. Then what? You die. Then what?
Then what? No, seriously, then what? My atheist friends say "nothing, you just cease to exist". Okay, so why bother? Before I am born I am insignificant, and after I die I am insignificant, but somehow between life and death I have significance?! The Bible talks about our lives as being a vapour (James 4:14). When you made your tea/coffee this morning, and a vapour 'birthed' from the surface, rose up then disappeared, was that event significant? Without meaning and significance life is a cruel joke! It is absurd! You may have superficial meaning between birth and death, but _ultimate_ meaning? No. Been there, done that. Just keep asking yourself those two words "then what" and you'll reach the end of yourself and your reasoning in complete despair.
But there is hope. To know Jesus, personally! I do! I know you probably don't believe me, but it's because He lives I can face tomorrow. Because He lives all fear is gone. And I know He holds the future, and life is worth the living just because He lives.
If Jesus Christ did not rise from the dead, then my hope dies too. The great mathematician Blaise Pascal condensed it into a simple wager: https://en.wikipedia.org/wiki/Pascal%27s_Wager
