Isaiah 50:5-7 RSV — The Lord GOD has opened my ear, and I was not rebellious, I turned not backward. I gave my back to the smiters, and my cheeks to those who pulled out the beard; I hid not my face from shame and spitting. For the Lord GOD helps me; therefore I have not been confounded; therefore I have set my face like a flint, and I know that I shall not be put to shame;
Isaiah 50:10-11 RSV — Who among you fears the LORD and obeys the voice of his servant, who walks in darkness and has no light, yet trusts in the name of the LORD and relies upon his God? Behold, all you who kindle a fire, who set brands alight! Walk by the light of your fire, and by the brands which you have kindled! This shall you have from my hand: you shall lie down in torment.
Even in darkness, we are to follow God’s guidance. When we light our own fires and trust in our own wisdom, we will face the torment of our hubris.
