When the final work in the vineyard begins, and the natural fruit reappears, the process of casting the bad branches producing bitter fruit accelerates. The bad is cleared away to make room for the good. (5: 74.) The remaining gentiles will be swept away and their cities will be inhabited again. This time they will be swept away by the natural fruit, to whom the land belongs. (3 Ne. 22: 3.)
Though there are two gatherings in the last days, when the natural fruit returns it will be to both. Servants will minister to both. They will all be gathered in, and Israel will gather together in Zion and the long dispersed of Judah will also be given their land in peace. (Isa. 11: 12.) The Lord will hasten His work when the natural fruit reappears. (D&C 88: 73.) Some will say it is like before and everything continues from day to day uninterrupted and the Lord delays His coming. (Luke 12: 45.) Some will think the Lord will allow everything to be destroyed and still not return. (D&C 45: 26.)
Then will be the time when “they became like unto one body” though gathered in both Zion and Jerusalem. (5: 74.) Zion will have her kings (D&C 133: 32) and Judah will have her prophets. (See Rev. 11: 3; D&C 77: 15; Isa. 51: 19-20; Zech. 4: 11-14.)
It begins with the regrafting. Joseph Smith began that process. The purpose was to establish a relationship where it is possible for natural fruit to return. It would take generations before the natural fruit would reappear.
In the work to reestablish the natural fruit, the Lord of the vineyard would send both servants, like Joseph Smith, and He would work alongside them. In other words He would appear to them. (See JS-H 1: 17-19; D&C 84: 35; D&C 93: 1.) The Lord will be present for the work of producing natural fruit in the last days. He will appear to them, and both He and the Father will take up their abode with them. (John 14: 23.) These will be those who are the natural branches, capable of producing the fruit for the final harvest. (John 15: 4-5.) This is the culmination of the final chapter in the vineyard. His work and glory is to bring this about. He knows the end from the beginning. His work has always pointed to this great, final labor.
Those who will be gathered will not need to tell one another to “know ye the Lord” for those who remain will all know Him, from the least to the greatest. (Jer. 31: 34; D&C 84: 98.) These are those who have been redeemed from the fall, for they have been back into His presence. (Ether 3: 13.) These are those who receive a testimony from Christ that they are saved. (D&C 76: 51.) Those who claim to follow prophets, but have not received the testimony of Christ that they have part with Him will be burned at His coming and appointed their place in sorrow and suffering. (D&C 76: 98-106.)
There will be no lukewarm saints allowed to stand in that day. If they have received and followed the truth, they will be saved. If they have not, they will be gathered in bundles and burned. The result will be an era of peace in which the entire vineyard, as if one body, produces again natural fruit. (5: 75.) There will be joy at that day. The Lord and His servants will rejoice, and the Lord will give praise to those servants who labored with Him. (Id.) When He could take credit, instead He shares it. And He promises to those servants: “behold ye shall have joy with me because of the fruit of my vineyard.”
