I chronicles focuses a lot on David’s service to God and God’s resulting blessings to David. It reminds me of one of Psalm 1, which talks about the person who keeps God’s laws.
That person is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither—
whatever they do prospers. – Psalm 1:3
For a long time, I’ve resisted the claim that ‘whatever they do prospers’. It might seem like a silly thing to do, but if I don’t believe that God blesses whatever the righteous do, then I won’t feel disappointed when my endeavors fail. Now that I’ve said that aloud, it reveals two things. Firstly, that, somewhere deep down, I consider myself the kind of person described in Psalm 1 and secondly, that I believe that God doesn’t really guard the endeavors of the righteous like the passage says. The first seems like hubris – but what can I do about it? The second bears further investigation. I can’t remember when I first began to think that way, nor can I remember why. I can’t even remember what God failed to give me that resulted in this belief, but 1 Chronicles says otherwise. God gave David victory over his enemies because David obeyed God. God blessed Abraham and Solomon too because they followed him.
It does bear mentioning, however, that in both cases God specifically promised those people that he would bless them.
