The Savior gave the Nephites scripture they didn't have -- the words of Malachi. This same message was given to Joseph Smith. The centrality of the keys of the sealing power restored by Elijah the Prophet to Joseph Smith in 1836 is evident in the repitition of this brief passage of scripture in multiple places in the standard works.
2 But unto you that fear my name, shall the Son of Righteousness arise with healing in his wings
I'm grateful for the healing power of the Savior of the world, the Son of the Almighty Father. When I look up at a soaring hawk, I think of this image of the Son of Righteousness rising up above all things. He can see over all and knows our needs and is prepared to provide comfort to all who believe in Him.
