Joy is abiding, like a still, steady light. The light flashes only as the lens of gratitude-for-all-things passes over the light.
Joy is not the same as peace. Peace can be merely contentment or the lack of chaos. Joy shines out in the darkness. Joy abides even when peace is shaken by turmoil and torments of the stormy world.
Our soul, the creation of God the Father, is a lighthouse. Joy is the light of the Holy Spirit within. Gratitude is the lens. The Son of God is our Lighthouse Keeper.
