The Psalms are at the same time deeply personal songs borne out of struggle, and yet they are often given “to the choirmaster” for the congregation of Israel to sing. These songs are the battle cries of those fighting “the good fight of faith” (2 Timothy 4:7); they are weapons in our hands and sparring partners to train us how to pray and fight as we walk with the Lord in this world.
Psalm 1 invites us to see an individual blessed man and to realize that we are not Him. But we are invited to be united to Him, to have His life as our own, to have His delighting as our own, and to have His obedience as our own.
