That’s not my argument at all but it seems you’re not interested in that

Fair point, what I meant is that in relation to being saved, it’s irrelevant he is rich because only God can save people. In relation to the hardships you’d face with being a Christian and rich it’s valid.

I am a Christian and I think your argument is weak. That Jesus talks of a rich person here is irrelevant, the core of Jesus teaching is that salvation is a gift freely given, but not something we can obtain in our own power.

Grew up with this stupid interpretation that it refers to some small gate in Jerusalem that camels had to bend down to use or something.

Jesus literally gives the answer in the next sentence:

”Indeed, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God.” Those who heard it said, “Then who can be saved?” He replied, “What is impossible for mortals is possible for God.”“ ‭‭Luke‬ ‭18‬:‭25‬-‭27‬ ‭NRSV‬‬

God can save anyone. And my layman’s interpretation on top of it, no man can save himself.
