How I wish I could link to a sound clip of the Nephi musical, With Mine Own Hand. This is one of my favorite songs, especially v. 22 & 23. (I can share the trailer for it.) The music for "most joyous to the soul" conveys the utmost joy. As it should.
For the love of God was made manifest to us through Heavenly Father's beloved Son, who came to teach us how to live, then allowed himself to be sacrificed for our sins, and then was resurrected which opened up the door for our being resurrected one day after we die. But that wasn't it. He is still there for us every day to give us continued guidance and comfort. He is the greatest reason that we have to rejoice.
