Chapter 13 - Preparing investigators for baptism and confirmation.
Principle - Missionaries help those who are converted prepare for baptism, confirmation, and membership in the Lord's church.
Exodus 20:8-11 - As members, we must set an example for those converts. We are instructed in this set of scriptures that we must remember the sabbath day, to keep it holy. It is important that converts can see that members are strong in keeping the faith helping them to keep it themselves. We must work to support the missionaries in teaching this principle.
Amos 3:7 - This scripture is written that we may follow the words of the prophets and heed to their warnings. God does reveal his secrets to his servants, the prophets. It is the responsibility of the prophets to relay that message to the members of God's church. And as members of God's church, it is our responsibility to obey these words as if they are the words of our Heavenly Father.
Principle - Covenants and ordinances necessary for exaltation are received in the house of the Lord.
Doctrine & Covenants 131 - Celestial marriage is required in order to obtain the highest degree of glory in heaven. Celestial marriage is one of the required ordinances to live with our Heavenly Father again. We must live worthily to be able to enter into the temple with our partner and be sealed for time and all eternity.
Doctrine & Covenants 132:15 - It is written in this scripture that any marriage between a man and a woman that are not married by the word of our Heavenly Father, their covenant and marriage are not of force when they are out of the world. This is just another reason why it is so important for us to be worthy of a temple marriage so that our marriages can be continued in the after-life that we can be with our spouses forever.
