Isaiah 64:6: Our Righteousness Like Polluted Garments
Isaiah 64:6 is a corporate confession, not a denial that obedience matters. It says that deeds done by a stained people cannot be the ground on which anyone stands before God, and it points the only hope to God himself.
1 John 1:5–10: Walking in the Light
The message John announces is that God is light, and that message sorts people by how they walk, not by what they claim. Sinlessness is self-deception; confession rests on God's faithfulness and righteousness.
