Then this [144,000 which is also known as the] “Holy City, new Jerusalem, the Zion of God, the Tabernacle of God, the Bride the Lamb’s Wife, the Mother of us all,” is a City, enclosed with a wall one hundred and forty-four cubits high, which embraces the “garden of Eden, the Paradise of God.” And God calls it his “SANCTUARY.” Learn more here: The Opening of the Heaven's by Captain Joseph Bates.

"Another question upon which we had some conversation was in regard to the elect of God—that the Lord would have a certain number, and when that number was made up then probation would cease. These are questions you or I have no right to talk about. The Lord Jesus will receive all who come unto Him. He died for the ungodly and every man who will come, may come. ¶ Certain conditions are to be complied with on the part of man, and if he refuses to comply with the conditions, he cannot become the elect of God. If he will comply, he is a child of God, and Christ says if he will continue in faithfulness, steadfast and immovable in his obedience, He will not blot out his name out of the book of life but will confess his name before His Father and before His angels. God would have us think and talk and present to others those truths which are plainly revealed, and all have naught to do with these subjects of speculation, for they have no special reference to the salvation of our souls." — Manuscript 26, 1885. — Selected Messages, Vol. 3, p. 315.3-4 • Ellen G.
