Human lives are hard, even those of health and privilege, and don't make much sense. This is the message of the Book of Job: Any snappy explanation of suffering you come up with will be horseshit. ↗
Prayer is not a means of removing the unknown and predictable elements in life, but rather a way of including the unknown and unpredictable in the outworking of the grace of God in our lives. ↗
God does say He will graciously entertain our prayers. He says that if we exercise faith, and if our request is in accordance with His will, He will hear us. ↗
Prayer does not use up artificial energy, doesn't burn up any fossil fuel, doesn't pollute. Neither does song, neither does love, neither does the dance. ↗
