CHRISTINA - A question that's been bothering me - I am not LDS but what makes me excepted from being sealed to my husband for eternity? Just because I wasn't sealed in the temple doesn't mean I can't say "Honey, want to be sealed together forever?" and he says "Sure". BAM! We've sealed ourselves.
So now we're in Heaven - do you really think God would say "sorry, not LDS, no temple sealing, no together forever" or don't you think He'd say "Of course, come on in!" Our God is a loving God regardless of our faith and would accept our "own" sealing ordinance even if we're not LDS. I don't think He'd turn us down! Of course we said "till death do us part" in our vows, but I don't think we're any less cherished in His eyes because we're not "officially" sealed. JMHO.

JOEL - I guess this depends on if you believe in the Bible or not. You can believe what you want about your own marriage, but most Christian religions do not believe that a civil marriage lasts beyound the grave. They find support in this belief by what Jesus said in the book of Matthew:

23 The same day came to him the Sadducees, which say that there is no resurrection, and asked him,
24 Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother.
25 Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother:
26 Likewise the second also, and the third, unto the seventh.
27 And last of all the woman died also.
28 Therefore in the resurrection whose wife shall she be of the seven? for they all had her.
29 Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.
30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. (Matt 22:23-30)

Here Jesus explains that anyone involved in a civil marriage will no longer be married in heaven, but will be angels. However, when Jesus ordained His Apostles and gave them priesthood power He said:

"And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven."(Mat 16:19)

They would now have the power and authority to bind couples in the eternal marriage covenant on earth that would be bound in heaven as well. And in talking about marriage Jesus said,

"Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder."(Mat 16:19)

In other words, once God has joined two people together, through an authorized representative, no other earthly man can declare that they can ever be separated. Through latter-day revelation we have learned how a couple can be sealed together forever, using the same authority Jesus gave His apostles.
