"The new and everlasting covenant" is composed of "all covenants, contracts, bonds, obligations, oaths, vows performances, connections association or expectations" [1] that God invites his children to enter into by the Holy Spirit (ie: ratified as in effect by the Holy Ghost). These covenants referred to are entered into in conjunction with God's authority and power.
The new and everlasting covenant is also called "the fullness of the gospel"in part, I believe, because it reminds us that we are ultimately called to enter into a complete (full) commitment/covenant to incorporate every part of Jesus's gospel into our lives, covenanting ourselves to being fully united with God; to take upon ourselves the name of Christ.
The new and everlasting covenant includes, therefore, all covenants that we make to more fully live the gospel of Jesus Christ. Those covenants include covenants we make at baptism, during the sacrament, when we marry, when we receive priesthood ordination or priesthood power, etc.
"The new and everlasting covenant of marriage" is the gospel marriage covenant, made in conjunction with God's authority and power, and made between God and two of his children who are in, or who are entering into, a marriage. It involves a man and a woman giving themselves to each other to be husband and wife in a holy marriageand, like every covenant, each of them, individually, solemnly makes a covenant to the Lord that they will be faithful to the principles of the gospel of Jesus Christ in their marriage; loving and caring for each other.
This covenant also involves a covenant and a promise, on God's part, to seal upon those individuals, certain, specific, heavenly blessings and power to act in godly ways, pronounced by someone who has been given God's power to do so,which, covenant "in the process of time" may "sealed by the Holy Spirit of Promise". They are reminded that the efficacy of the sealing of those blessings and power to act is dependent upon their faithfulness to the Lord. And none of those blessings say anything about people being "sealed to each other". Specific blessings are sealed upon them dependent upon their faithfulness. Being "sealed to each other" is not one of those blessings.
In the temple marriage ceremony what is sealed is the promise of blessings upon each of the two individuals involved, both the husband and the wife, with counsel that their receiving those blessings, individually, depends upon their respective faithfulness to the Lord, and their living the principles of His gospel throughout their lives. This is not an ordinance that is focused on who lives with whom. It is an ordinance that invites us, as individuals, to live holy lives in our relationships, and to be prepared, therefore, to receive the grace and glory that God hopes we will embrace with joy. This is a classic gospel covenant pattern.
Contrary to Latter-day Saint vernacular and happy but theologically sloppy Primary songs, and even the occasional misuse of the phrase in church manuals, a husband and wife are not "sealed to each other" in the temple. Rather, each individual enters into a "new and everlasting covenant of marriage" before God, promising to God that each will, individually, seek to create a holy marriage; a marriage upon a full commitment to the principles of the Gospel of Jesus Christ. They are also pronounced married and in a marriage relationship that may (if they individually keep the covenants into which they have entered) last beyond this life. and divine blessings are conditionally "sealed" upon them dependent upon their individual faithfulness to the commitment they have made. Again this is a classic gospel covenant pattern.
Temple marriage "sealings', in other words the things that are actually sealed in a marriage in a temple, are not sealings (bindings, tying, gluing eternally into the same celestial relationship) of two people to each other. Temple marriage sealings are actually provisional sealings of specific future blessings upon individuals who have made specific promises to God to live a holy life in their marriage.
The blessings that are sealed upon them are dependent upon their individual faithful keeping of their promise to live by the word of God in their marriage thoughout their lives and beyond. Those blessings are blessings that, like the blessings of other holy covenants, are ones connected to and are a result of one's efforts to live a holy, or celestial, life.
We are not "family groups" to God (though He does delight in a good and loving family). We are, first and foremost, His individual, beloved children.
