So, what is required for a family to be exalted forever? We qualify for that privilege by making covenants with God, keeping those covenants, and receiving essential ordinances.
This has been true since the beginning of time. Adam and Eve, Noah and his wife, Abraham and Sarah, Lehi and Sariah, and all other devoted disciples of Jesus Christ—since the world was created—have made the same covenants with God. They have received the same ordinances that we as members of the Lord’s restored Church today have made: those covenants that we receive at baptism and in the temple.
