New Defender's Study Bible Notes
1:13 power of darkness. The “power of darkness” (note Luke 22:53) is nothing less than the kingdom of Satan, in which we all once were captive slaves. Note, for example, Ephesians 2:1-3. However, we have now been set free from this bondage and carried into a new kingdom of light rather than darkness (note Colossians 1:12).
