And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people, and God Himself shall be with them, and be their God. – Revelation 21:3
Mark, that in all Christ has, a believer has a share. This seems to me to be the sum total, and the crowning of it all- to reign with Christ, to ride in His triumphal chariot, and have a portion of His joy; to be honored with Him, to be accepted in Him, to be glorified with Him. This is heaven, this is heaven indeed.
Well said Chrysostom, “The pains of hell are not the greatest part of hell; the loss of heaven is the weightiest woe of hell;” to lose the sight of Christ, the company of Christ, to lose the beholding of His glories, this must be the greatest part of the damnation of the lost. Oh, you that have not this bright hope, how is it that you can live? You are going through a dark world, to a darker eternity. I beseech you stop and pause. Consider for a moment whether it is worth while to lose heaven for this poor earth. What! pawn eternal glories for the pitiful pence of a few moments of the world’s enjoyments? No, stop I beseech you; weigh the bargain ere you accept it. What shall it profit you to gain the whole world and lose your soul, and lose such a heaven as this?
But as for you who have a hope, I beseech you hold it fast, live on it, rejoice in it-
“A hope so much divine,
May trials well endure,
May purge your soul from sense and sin,
As Christ the Lord is pure.”
