"TEMPLE MARRIAGE (SEALING OF SPOUSES). [The sealer sits at the head of the altar with two witnesses, one seated at his right and the other at his left. The bride and groom kneel at opposite sides of the altar, facing one another, clothed in the robes of the holy priesthood. They take each other by the right hand in the patriarchal grip.] SEALER: Brother _________, do you take Sister _________ by the right hand and receive her unto yourself to be your lawfully wedded wife, for time and all eternity, with a covenant and promise that you will observe and keep all the laws, rites, and ordinances pertaining to this holy order of matrimony in the new and everlasting covenant; and this you do in the presence of God, angels, and these witnesses of your own free will and choice? GROOM: Yes." (Sealings)
"SEALER: Sister _________, do you take Brother _________ by the right hand and give yourself to him to be his lawfully wedded wife, and receive him to be your lawfully wedded husband, for time and all eternity, with a covenant and promise that you will observe and keep all the laws, rites, and ordinances pertaining to this holy order of matrimony in the new and everlasting covenant; and this you do in the presence of God, angels, and these witnesses of your own free will and choice? BRIDE: Yes. SEALER: By virtue of the holy priesthood and the authority vested in me, I pronounce you, _________ and _________, legally and lawfully husband and wife for time and all eternity; and I seal upon you the blessings of the holy resurrection, with power to come forth in the morning of the first resurrection, clothed in glory, immortality, and eternal lives." (Sealings)
"I seal upon you the blessings of kingdoms, thrones, principalities, powers, dominions, and exaltations, with all the blessings of Abraham, Isaac, and Jacob; and say unto you: be fruitful and multiply and replenish the earth, that you may have joy and rejoicing in the day of our Lord Jesus Christ. All these blessings, together with all the blessings appertaining unto the new and everlasting covenant, I seal upon you by virtue of the holy priesthood, through your faithfulness, in the name of the Father, and of the Son, and of the Holy Ghost. Amen." (Sealings)
Through the temple sealings, people receive the exact same blessings as Jesus. You may not have known this before, but after reading in Daniel, you will see how the Son of Man received dominion, glory, and a kingdom. Jesus is that Son of Man, which we also know as our Lord and our God. Now let's read what blessings were bestowed upon Jesus, while remembering that in red, the couples that are sealed receive the same blessings and more. Daniel reads, "I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him. And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed." (Daniel 7:13,14) Notice how Jesus's dominion and kingdom are singular, but for Mormons it's plural. This is blasphemy. The new covenant is not of God, but of Satan. He loves to take away God's glory and give it to people instead.
Jesus also taught that there is no marriage in heaven. It is written, "the same day came to him the Sadducees, which say that there is no resurrection, and asked him, saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother. 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: Likewise the second also, and the third, unto the seventh. And last of all the woman died also. Therefore in the resurrection whose wife shall she be of the seven? for they all had her. Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven." (Matthew 22:23-32) This passage is in Matthew, Mark, and Luke, and Mormons despise this teaching from Jesus. So what side are people on when they choose to believe in eternal marriage? The devil. Amen.
They can be sealed all they like. Jesus said there’s no marriage in heaven.
