The exact phrase spiritual bondage does not appear in the Bible, but Scripture does speak of unbelievers’ being in bondage to sin (Acts 8:23; Romans 6:6, 16, 19; 7:14; 2 Peter 2:19). Jesus said, “Very truly I tell you, everyone who sins is a slave to sin” (John 8:34) and that He came to set us free (verse 32). Evil has a way of taking hold in a person’s life, and bad habits are hard to break. For an unsaved person, sin forms a chain that only the Savior can break.
