The allegory has a "long time" in which the vineyard produces natural fruit. (5: 76.) This peaceful and productive era is Paradisiacal. (See Articles of Faith, 10.) The vineyard will allow the Lord to "lay up the fruit of [His] vineyard" because there will be an end to this era of the vineyard. (5: 76.) There will come a time for final accounting. The vineyard will need to be re-created, and a new one brought in its place. But before that day the vineyard will produce "for a long time, according to that which I have spoken." (Id.) During that time Satan is bound and children grow up without sin.
The story of the end of this creation culminates in the last, great day, when Satan is loosed again for a season: "But when the time cometh that evil fruit shall again come into my vineyard" will happen after the period of Paradise. In the allegory, it is when "evil fruit" returns. In John's vision it is when "the thousand years are expired." (Rev. 20: 7.) John describes how "Satan shall be loosed out of his prison" at that time. (Id.) When he is, he "shall go out to deceive the nations which are in the four quarters of the earth." (Rev. 20: 8.)
Despite all the Lord of the vineyard has done for His trees, the accuser will still find fault. The things of God will again be challenged, criticized, debated, accused and maligned. The Lord's motives will be questioned, and His means will be derided. Why so little natural fruit? What right is there to discard the bitter fruit? Is not the worth of each soul great enough the Lord of the vineyard should have done more? Why should so much of the fruit have been gathered and burned? How can the Lord have the best interests of the vineyard in mind when there were so many who have not been gathered as natural fruit? What of those who came into the vineyard and were produced through wild branches, how can it be fair to leave them for the burning when they were given an unfair challenge? Their plight is not of their own making, and the Lord of the vineyard is unfair!
You see it is one thing to claim you believe in and follow the Lord when in your mistaken arrogance you assume His plan requires nothing from you and will exalt you to the sides of the north. (See Isa. 14: 12-13.) But it is another thing when you realize "the summer shall be past, and the
The Lord of the vineyard has done all He could, and respected the agency of men. The arguments at the end of the Millennial Day will prevail. John reports that the number of those who align with the accuser will be so much greater than the camp of the saints, that they will "compass the camp of the saints about" because their numbers so vastly exceed the mere "camp" of the righteous they will be able to entirely surround them. (Rev. 20: 9.)
These rebellious branches are "burned with fire" (5: 77) or, as John describes it, "fire came down from God out of heaven, and devoured them." (Rev. 20: 9.)
This then leads back to the major themes of the allegory. It was included by Jacob for us so that when these things come to pass we are not left surprised or wondering why we were not warned by the Lord.
