This song is about being there for each other, I believe.
where he starts with Hey Brother or Hey Sister, he is trying to tell or teach his brothers and sisters (which I do think can be either family or other loved ones) something about their lives: brother, there is so much left to do in life, even what you did can feel as new; and sister, know when you need to be serious.
And asking if they are still able to trust their love, which makes me think they already have had a hard time.
For any other hard times coming up for his brothers and sisters, he is going to be there for them no matter what, obviously. All the other pieces of lyric are pretty much about that. Also, I think the bros and sisters he is talking to are younger or can really need some help, because they may be vulnarable in some way. that is because of those questions in the chorus like What if I lose it all?
