Why can’t a Christian believe in life in a multiverse?
We know God exists. We know Heaven and Hell exists. We know Heaven is not in the sky, and hell is not below ground.
Why can’t God be an omnipotent being from a dimension that we can’t perceive?
I believe science allows us to better see God’s wonders.
What better than an extra-dimensional Being, and location explains the existence of the Divine?
We will never know in this lifetime, because God requires Faith, but the possible scientific plausibility of the theory has the potential to bring millions to God’s Love.
How does one feel about eternal life on the surface of a star? Kinda sounds like Hell, huh?
The fundamentalist argument against this is that Jesus died once for all our sins and there's no way that his dying on a cross on Earth could be communicated to sinners on other planets. Therefore there must not be sinners on other planets. Therefore no extraterrestrials.
There are at least three different ways we can have multiverses. The one proposed by Hugh Everett has some negative potential consequences. If every possible outcome of a quantum effect occurs, then it could be the case that sometimes when you choose to do the right thing in one universe you necessarily do the wrong thing in another. If this happens then there is no way to make sure that all of your selves behave properly and there is no hope for at least some of your multiple souls.
And if you are a Calvinist and believe that we have no real input in our salvation then you might have to believe that some of your multiple souls are elect and some are not or that God so arranges it that all souls in all multiverses of the elect are saved.
