What a beautiful quote. So often we tend to think that joy comes from circumstances around us: "If this or that happens, I will be happy. If only things weren't the way they were, I think I would be so much happier." Yet joy does not come from unbroken sunshine, like this quote says. God has designed us to find perfect joy and fulfilment in Him; as we rest and trust in Him, we see His faithfulness and goodness and are overwhelmed with "joy unspeakable and full of glory." Total dependence on Christ is, indeed, the highest pinnacle of our spiritual life.
