The psalmist might proclaim that the earth is the Lord's but we live as if everything belongs to us. It's more than not taking care of the portion of the planet we inhabit. Rather our neglect of good things is a symptom of a more serious disease. As the old confession goes we have sinned against the Lord in thought word and deed by what we have done and left undone. Our hands are unclean, our hearts are impure and deceit comes naturally to us. And so it was for the unclean and impure that the King of Glory climbed a hill called Calvary where his clean hands were nailed to wood and his pure heart was broken. The blessing of the Lord we receive is the answer to the prayer of another psalm. Create in us clean hearts, O Lord, and renew in us a right spirit. Such is the company of those who seek the Lord. Not those who are pure in their own right but those who have been vindicated by the God of their salvation and that is good company indeed.
