Joel 2:23 Be glad then, you children of Zion, and rejoice in the Lord your God: for he hath given you the former rain moderately, and He will cause to come down for you the rain, the former rain, and the latter rain in the first month.
The latter rain spoken of in the above verse has to do with the outpouring of the Holy Spirit which is scheduled to be ramped up significantly just before probation closes so as to bring all of earth’s teeming multitudes to maturity, where their final irrevocable choices will be sealed for eternity. This includes those who will ultimately be saved in God’s kingdom, and also those who will be eternally lost.
The valley of decision referenced in the book of Joel 3 has to do with final decision-making for every person living on the planet at that time, and even now. The decision is as simple and straightforward as it gets: if individuals choose to obey God rather than men, they would need to step up to the plate, and cast in their lot with the commandment-keeping people of God. In other words, to put it in precis form, the gospel in our day can be condensed in a nutshell by these few words: “If you love me, keep my commandments, including the 7th day Sabbath of the decalogue.
But if not, then a definitive, and deliberate choice to worship the beast and his image, would have to be made, but any which way, the power of decision will then be actively engaged either for, or against God. The work of the latter rain as will be ordained by the Holy Spirit will cut away all of those nonessentials to salvation that have been accumulating for centuries, and God will make present truth so simple that even a child could understand.
Joel 3:13 Put you in the sickle, for the harvest is ripe: come, get you down; for the press is full, the fats overflow; for their wickedness is great. 14 Multitudes, multitudes in the valley of decision: for the day of the Lord is near in the valley of decision.
May The Lord add His blessing to the study of His word. God bless!
