Lesson #8 The Covenant Relationship is the fullness of the gospel.
There are four references in the D&C relating the fullness of the gospel to the covenant relationship. Sec 1 and 108 and two others. Sec 1 and 108 both have a form of Hebrew poetry called a chiasm with a double center point dealing with the fullness of the gospel and the covenant. Being in a double center point tells us that both terms mean the same, therefore the fullness of the gospel is the covenant relationship.
Actually it should be obvious even if there were no exact scriptures that said as much. If you give your all, you give your fullness. Giving your all is what the covenant relationship is. A good verse describing the covenant relationship is Omni 1:47 "Yea, come unto Him and offer your whole souls as an offering unto Him...". The essence of the covenant relationship is caught up in Jesus' prayers in 3N 9:23, 30. He prayed the same thing twice"...that I may be in them as Thou, Father, art in Me, that We may be one." The Father was in Jesus 100%. If Jesus is in us 100% then we have totally died to self and given our all, our fullness. The prayers of Jesus will be answered. There will be people in this category. The second step of the ancient Hebrew covenant is the exchange of weapons belts which means that each party will defend the other even if it means losing your own life. Jesus has already died for us. He is now waiting for us to die for Him. This is why the covenant relationship is so powerful. It is stronger than life itself. It overcomes the fear of death and all other fears.
Additional evidence equating the fullness to the covenant is found in two verses already discussed, Alma 9:18 and 3N 9:92. Alma 9:18 talking about knowing the mysteries in full if we do not harden our hearts. In full means fullness. We now know that to not harden means to have a covenant (3N 9:92). Therefore, covenant means fullness. We talk about the fullness of the gospel all of the time, but until recently, we have not been talking about the covenant relationship. It is possible that we have been using a watered down definition of the fullness of the gospel in the past? After all, there are four definitions for every spiritual concept.
