Psalm 119:55-56 (ESV):

I remember your name in the night, O LORD,
   and keep your law.
This blessing has fallen to me,
   that I have kept your precepts.

This is an interesting translation of this scripture. No other version that I read used that word “blessing” in verse 56. Whether the translation is the best, I don’t know. But I think the sentiment is apt nonetheless.

To obey God is a blessing from God which stands in a bizarre tension with our own human responsibility for our actions.

But whether direct or indirect in influence, all good things come from God—with all the evil that my hands have the potential to perform, it is God that keeps me from the worst of it.
