it sounds almost like a conversation between david and his brother, and his brother is worried, not for himself, but for david, because he won't be there to support his baby brother like he always has been. so he's reassuring david that he'll always be there, in spirit if not in person. and then it switches to david, who sees the suffering his brother goes through and wishes he could make it go away or even switch places with him, but his brother is still saying that no matter what happens, it'll be okay. david isn't at peace with things but his brother is, and david was so moved and inspired he wrote a song.
