If you believe in an afterlife, what will it be like for people who are not part of your religion? Or for people who don't share your religious/spiritual views? Or is what happens to us after death independent of our beliefs or affiliations?
There are several options depending upon choices made and the opportunities had.
Option 1. For those who did not have much of a chance in this life they will have it in the spirit world to embrace Christ and be a joint heir with Him the same as those who followed Him here. (Glory likened unto the sun)
Option 2. For those who generally live good lives, but choose to not make Him a priority they will have a heaven, but miss out on the greater blessings and opportunities Option 1 folks have. (Glory like the moon)
Option 3 The wicked and evil who refuse to repent in this life and the next will suffer for their own sins and in time be redeemed to type of heaven. (Glory like a star from earth's perspective)
Option 4. For those who knew Christ and turned from Him and fought against Him there is an eternity of misery without relief. This is a rare thing.
Put another way we will rise as high as we are willing to go. If we don't live the law of a given kingdom we can't be there. God is loving, has great mercy and is also just.
One of the great beautiful things here is that no one missis out due to no fault of their own.
