Reincarnation: Is there an advantage for non-believers?

[zenmaster]

If reincarnation exists, then why would all these souls keep deciding to come back as Christians that don't believe in reincarnation?

To make that statement, you must be assuming they are the same souls. Simply look at the population growth.

So you would speculate that most of these are in their first incarnation? But even so, there is some knowledge of what they are getting themselves into.

It's an expression of the 4th sub density here, so no not 1st incarnation by far. However an important one because around that stage is when you start choosing your incarnations. Look up blue valuing meme.
