148. How will the cessation of death be brought about at the end of the thousand years?

149. Will those who live as mortal men during the reign of Christ have it in their power to become immortal at the end of the thousand years?
Answer: Yes; if they please God, they will enter into life at the end of the thousand years, just as those do who enter into life at the beginning of that period. If they die before that time, they will then be raised and glorified. If they are alive, they will be changed. Their number will be much greater than the number of those who become immortal at the beginning of the thousand years. They will be the harvest, while those accepted at the coming of Christ will be but the first-fruits.

And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: And they shall see his face; and his name shall be in their foreheads. And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever. (Rev. 22:3-5).

For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea. (Hab. 2:14).

And he built his sanctuary like high palaces, like the earth which he hath established for ever. (Psa. 78:69).

But the meek shall inherit the earth; and shall delight themselves in the abundance of peace. The wicked plotteth against the just, and gnasheth upon him with his teeth. The Lord shall laugh at him: for he seeth that his day is coming. The wicked have drawn out the sword, and have bent their bow, to cast down the poor and needy, and to slay such as be of upright conversation. Their sword shall enter into their own heart, and their bows shall be broken. A little that a righteous man hath is better than the riches of many wicked. For the arms of the wicked shall be broken: but the LORD upholdeth the righteous. The LORD knoweth the days of the upright: and their inheritance shall be for ever. (Psa. 37:11-18).
