What happens inside Mormon Temples?

So, Inside the temple there are three main things that happen. Baptisms on behalf of those who are dead a ceremony called an Endowment and Marriage for Eternity.

1 Corinthians 15:29 "Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they than baptized for the dead?"

Baptisms for the dead is something that was practices in the days of Jesus Christ, It comes from that First Baptism is required for everyone to enter into the Kingdom of heaven, and second that salvation is available to everyone who has ever walked on the earth.

What happens is members of the church go into the baptismal font and are baptized on behalf of those who have died. Members can do this when they reach 12 years old or if they have been baptized a couple of weeks. The people who are baptized are baptized on behalf of someone who has passed on, Usually an ancestor of that person. The person who has passed on than gets to choose, weather they accept Jesus Christ and are washed clean through baptism. Or they can reject Jesus Christ. They still have that freedom to choose. So if they do not want it, they just reject it.

The Endowment is a ceremony that new members of the church take part in after they have been in the church for about a year. Here we learn more about the creation of the world, and make covenants with God in addition to the ones we make at baptism. To Endow someone means to give a gift, And that is really what the ceremony is, It is a gift from God. There to give us guidance and strength to deal with the challenges of life.

After the endowment comes the sealing room. Here couples and families kneel down together at the alter and make a vow to stay loyal to each other and support each other, not just in this life but forever. There are two mirrors on the walls in this room, opposite each other they reflect each other over and over, symbolizing that this is something that lasts forever. It is a very beautiful thing to see.

And that basically is what happens, The temple is God's university, as we go through we learn thing all the time and receive guidance and personal answers from God. I find it wonderful that each temple has on it the words "Holiness to the Lord, the house of the Lord" because this is the house of God on earth.
