Psalm 51:1-12 or Psalm 119:9-16
Two ways to refreshment and reorientation: Reapplication of the past and a shift of orientation toward the future. Both can bear much good fruit and when combined offer a quantum leap of presence in an iffy world.
This week count how many changes you ring on the past. This will give you a clue about your ability to not be bound by its tendrils.
This week count how well you are able to live with an ambiguous, guarantee-less future. This will give you a clue about your ability to wait for the prompting of Spirit.
