He who had known us before we were even born came to know us infinitely better as he knelt in Gethsemane and as he hung on the cross of Calvary. We come to know those we serve (Mosiah 5:13; compare 1 John 2:3-4). And we certainly come to love and treasure those for whom we sacrifice. Conversely, the depth of the pain we feel in behalf of a loved one is intimately tied to the depth of the love we bear that loved one. Thus only a being filled with infinite and eternal love could perform an infinite and eternal sacrifice.
