2 Nephi 2
I really don’t think that Lehi is preaching to Jacob here – he is simply conversing with a beloved son who has proven his faithfulness. Lehi is sharing some of the spiritual treasures in his heart with a son who appreciates them but this does not mean that the information is particularly new to Jacob. Lehi is bearing testimony, but the bearing of testimony is not restricted to those who do not already believe. In fact, it can be the sweetest when it is shared with others who already have similar testimony.
