I love the imagery of the tree planted by the waters and the old gospel hymn that proclaims that message. In a changing and shifting world, most all people yearn for stability of a giant tree with its roots firmly fixed in the earth. I too found myself humming a little Led Zeppelin. Not coincidentally, I believe I am being called to preach this in terms of the choice God offers us all. What I find interesting is how this contrasts with popular American ideology.
Independence is god.
Dependence is weak, disreputable, and disgraceful. What comes to my mind is the multitude of devices available that are intended to ensure happiness, fulfillment, and inner peace. Everything from designer clothes to designer drugs. Electronic entertainment and pornographic stimulation. This psalm reminds us that we don t have to make ourselves happy.
