Elder Jeffrey R. Holland of the Quorum of the Twelve Apostles explained that Christ and His Atonement should be at the heart of our rejoicings:
“Jacob’s testimony was that ‘the Mighty God’ will always deliver ‘his covenant people,’ and that the Mighty God is, by his own divine declaration, the Lord Jesus Christ, the ‘Savior and … Redeemer, the Mighty One of Jacob.’
“Jacob reflected on such teachings—especially those contained in the writings of Isaiah—so that his current audience and future readers ‘might know concerning the covenants of the Lord that he has covenanted with all the house of Israel,’ giving the parents of every generation cause to ‘rejoice’ and to ‘lift up [their] heads forever, because of the blessings which the Lord God shall bestow upon [their] children.’
“At the heart of that covenant and the reason for such rejoicing is the atoning sacrifice of that ‘Mighty God’ who is the Savior and Redeemer of the world” (Christ and the New Covenant [1997], 66–67).
