‘…They prosper in all they do.’ Sweet. Sorted, then? No action necessary, just go prosper. End of reading.
Or not. Let’s take it back to the context. In fact, go read the first six verses of Psalm 1. Ah, so there’s more to this ‘prosperity’ thing than simply kicking back and saying ‘alright God, hit my bank accounts with the extra zeroes’. Let’s start from the beginning.
‘Blessed is the man who walks not in the counsel of the wicked…but his delight is in the law of the Lord, and on His law he meditates day and night’ (Psalm 1:1-2 ESV). We have something to do, then. Our choices, whether we decide to spend time around people who drag us down, what influences we allow into our lives, how often we soak up God’s word…those things matter. And they’ll affect our productivity.
Verse 3 is all about that. It’s saying that, if we plant ourselves in God’s laws, we’ll flourish and produce fruit. That’s what it means to prosper. Prosperity isn’t necessarily a money thing. Psalm 1 suggests it’s anything that ‘yields its fruit in season’ (Psalm 1:3 ESV), so anything that bears good fruit. That’s something that blesses others, not just ourselves. It’s not just take-take-take. It’s as much about what we soak in, and what we give out, as it is about what we can get for ourselves.

What Now?
Find your closest stream, river, or lake, and go visit it. See if there’s anything growing alongside the river, like a tree. If there is, spend at least fifteen minutes sitting under it, and spending time with God. If you’re feeling extra-summery, take a picnic and a friend along for that prayer time.
