Don't forget the "saving ordinances" that must be performed on earth before one can dwell in Heaven where the Father and Son reside.
On lds.org we find this information:
"the Lord has prepared a way for them to gain a testimony of the gospel and receive the saving ordinances of the priesthood. These ordinances include baptism, confirmation, Melchizedek Priesthood ordination (for men), the endowment, the marriage sealing, and the sealing of children to parents."
"We all benefit from the influence of righteous priesthood leadership, and we all have the privilege of receiving the saving ordinances of the priesthood"
"Temple work is essential for both us and our kindred dead who are waiting for these saving ordinances to be done for them. Is there no chance for his escape?” 6 Fortunately our ancestors will have the opportunity to receive and accept the saving ordinances as we identify them and complete these sacred ordinances for them by proxy."
I don't see much about Jesus and his sacrifice there, but I see plenty about "earning" saving ordinances (works). I am so sorry for Mormons who are still wrapped in the bondage of a law and haven't found freedom through the atonement of Christ. I pray for them daily.

You forgot to mention the Temple is House of the Lord Jesus Christ and the Ordinances come from the Lord Jesus Christ
