New Defender's Study Bible Notes
2:15 deliver them. Even though Satan may have thought he had gained victory over God when God’s Son died on the cross, that very death assured his ultimate destruction (note Colossians 2:14,15; Revelation 1:18).
2:15 fear of death. The redeemed child of God no longer need fear death, for to him “to die is gain” (Philippians 1:21; see also Philippians 1:23; I Thessalonians 4:13).
2:15 to bondage. This pertains to our deliverance from spiritual bondage. See also Romans 7:23-25; 8:15.
