"And the opening of the prison to them that are bound."
The accomplishment of this promise can only be fulfilled in theresurrection of the just, when the graves will be opened, and all the bodies of the saints who have slept will come forth. See 1Cor.xv. 54,55: "So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory?" Then will death have no dominion over them, and the bonds of the prisoners will be loosed."
William Miller
