“And I will bring the blind by a way that they knew not; I will lead them in paths that they have not known: I will make darkness light before them, and crooked things straight. These things will I do unto them, and not forsake them.” – Isaiah 42:16
This is a prophecy of the Advent. And what an encouraging prophecy it is! It promises good, for it says, I, your Redeemer and Savior, when I shall come, will cause the spiritually blind to walk in new ways, I will lead them in new paths, I will turn their darkness into light, and straighten their poor distorted hopes and ideals so that their spiritual vision shall be clear and radiant with the light of heaven.
“I will bring the blind by a way that they knew not; I will lead them in paths that they have not known.” New ways and new paths! Our text is not speaking of any natural journey, but is referring to something spiritual when it uses these familiar terms of our natural life. The Psalmist prays, “Remove from me the way of lying,” and “Therefore I hate every false way.” And the same inspired penman speaks of the “paths of righteousness,” “the way of truth, “the way of thy commandments.” What are these ways and paths? Are they not those habitual ideals and forms of thought that lead the soul to the attainment of some purpose, whether good or evil? The modern psychologist speaks of pathways formed by habits in the substance of the brain. But how could there be these pathways in the brain substance if there were not corresponding pathways or “ways of thinking” in the life of the soul?
