Isaiah 49:24-26

24-26 We were lawful captives to the justice of God, yet delivered by a price of unspeakable value. Here is an express promise: Even the prey of the terrible shall be delivered. We may here view Satan deprived of his prey, bound and cast into the pit; and all the powers that have combined to enslave, persecute, or corrupt the church, are destroyed; that all the earth may know that our Saviour and Redeemer is Jehovah, the mighty One of Jacob. And every effort we make to rescue our fellow-sinners from the bondage of Satan, is, in some degree, helping forward that great change.
