In the Millennium we will not all belong to the same "church"

Without those to serve we could not receive the blessings that come from service.

and each type of service comes with it's own  rewards.

Serving a mission to spread the gospel is a special service with special blessings.

considering this line of thought it occurs to me that:

During the Millennium there will still need to be missionaries.
but won't the world all see God, wouldn't he just say ok folks were all going to be _____ you fill in the blank.

The basic principle of faith demands that he will not.

Even though he will be in our presence and we will be in the millennium there are many churches that will recognize the fulfilling of those prophecies, in fact most will according to their own religion. Can you imagine the confusion when a baptist and a catholic stand together in the millennium, both believing that their having survived to see Christ's descent from the clouds proves that they belong to the right church.

eventually someone will explain to them, that God wiped out the wicked, not the Wiccan.

and what I mean is that there are Good people have faith in God, Good people pray to him, and are struggling to do the very best that they can according to the dictates of their religion. There are even very good people doing the best they can with whatever information they have and do not believe in God at all. Would God destroy the righteous because they lack a title? No that would not be just. though righteous will be destroyed as a by-product of destroying the wicked.

The millennium will be a wonderful time, and I eagerly look forward to the return of our God.

it is amazing to me to see the eternal, universal, and inexorable principle in missionary work. and it amazes me how plain and simple and precious it is and yet here I am only just realizing it.
