In part 1 of this post, we talked about three characteristics of the blessed (as stated in Psalm 1), in the form of three questions: Whose advice are you following? Which path are you taking? Where are you sitting? Then we talked about what the delight of the blessed is: meditating on the Word of God.
In verse 3, the psalmist speaks of the characteristics of those who are blessed: the productivity of the blessed. The blessed one will be like a tree, planted by streams of water which yields its fruit in season. The leaves do not wither and in whatever they do, they prosper. These words say a lot about the productivity of a blessed (or happy) person.
