1 Nephi 11:22-23

"And I answered him, saying: Yea, it is the love of God, which sheddeth itself abroad in the hearts of the children of men; wherefore, it is the most desirable above all things.
And he spake unto me, saying: Yea, and the most joyous to the soul."

The Spirit of the Lord is showing Nephi the things he desires to know after Nephi had pondered the things his father, Lehi, saw. Nephi learns that the tree in Lehi's dream represents the love of God.  Nephi says that this love "sheddeth itself abroad." When Christ suffered in Gethsemane, he "shed" his blood for us all. It is interesting that the use of the word "sheddeth" alludes to the Savior shedding his blood.  The atonement was a pure act of love, and in so doing this the Savior shed love to every person.
I also love how the Spirit describes the love of God as being "most joyous to the soul." Doesn't that sound wonderful? I cannot think of anything that would give me more joy than to have the love of God always with me. I can feel that love at all times when I act as He wants me to. That is what brings true joy.
