In a blog post commentary on our Isaiah text this week, Anathea Portier-Young writes: Light is life (Job 17:1; 18:5, 18; 33:28, 30), goodness (Job 30:26), joy (Psalm 97:11), revelation and truth (Job 12:22; Psalm 43:3). It is linked with justice and righteousness (Isaiah 59:9) and the promise of salvation (Isaiah 49:6) and healing (Isaiah 58:8). Light is also what makes it possible to follow a path…What a simple summons then, to walk in the Lord’s light, in divine glory, in the path of God’s instruction. But it is not easy. What trust does it demand of God’s people, to be led by teaching and walking on the path revealed by truth? What fear must they put aside to call one another to be transformed in the practices of obedience and justice? What kind of courage enables a people to summon each other toward a future when nations who once ravaged and subjugated their homeland would call each other to the same obedience and justice, even to the same land and house?
