Well now that we have understood the principles and doctrines of the importance and significance of the Atoning Sacrifice of our Lord and Savior Jesus Christ, I'll now explain the blessings of this wonderful marvelous gift. Obviously the first thing the Atonement is going to do if we accept it through covenants is salvation.
Salvation from what though? Jacob says,"O how great the goodness of our God, who prepareth a way for our escape from the grasp of this awful monster; yea, that monster, death and hell, which I call the death of the body, and also the death of the spirit." Death and hell are overcome through the atoning blood of the Lamb.
However Christ is very specific on who the fulness of Salvation may be bestowed. John the beloved states in the Revelation 21:7,"He that overcometh shall inherit all things; and I will be his God, and he shall be my son." He also says this in Revelation 3:21,"To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne." This is the full purpose and blessing of the Atonement of Jesus Christ.
It isn't to just restore us to the glory Adam and Eve had in the Garden of Eden. It was to Exalt us. It's sole purpose was for us to return in honor to our Father and to become like Him ourselves. To believe that Christ's Atonement is not capable of this is also to believe that His Atonement was not infinite and is not capable of doing ALL THINGS! Christ says in the above mentioned scriptures that His atonement is to allow us to; inherit all things, become Son's and Daughter's of God, and to sit with Him in His throne just as He overcame and sit's with the Father in His throne. This was the purpose of God's Plan for you, that if you accepted Jesus Christ, were obedient to His commandments and overcame the temptaions and lulls of the world you may become just as He is.
