Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
Colossians 1:13 (KJV)
Notice that we are not waiting to be delivered, but that the Word says Jesus has already delivered us. As a result of the grace of God, darkness has no more power in the life of a Christian. And so let us declare victory over our lives every day, knowing that faith activates and accesses what grace has already provided.
