Charles Spurgeon Commentary Isaiah 42:7

"to open the blind eyes, to bring out the prisoners from the dungeon, and them that sit in darkness out of the prison-house." — Isaiah 42:7 (ASV)

Hear this, you who are melancholy, you who are despondent, you who cannot escape the prison of bad habits or shake off the chains of sin. Look, a liberator has come—one whose very mission it is to open the securely closed cells of sin and set the captives of Satan free.
