No photo needed for this one. "Dancing barefoot on knifepoints" is a metaphor, meta for how, in our daily lives, we have pains, hurts that we live with, endure because we must.
God is indeed good, but he doesn't promise us a rose garden without thorns on this side of the veil. He only makes it possible for us to continue to dance. There is a better, tear free life ahead of us, and our destination is well worth the journey.
