The last days weather patterns are certainly less predictable than just a few years ago. God’s covenant blessings of the right amount of rain at the right times were based on Israel’s obedience with faith in Him. Since this is still not the case, and since the times are nearing for God’s interventions in righteous judgments, then the lack of ‘good’ rain is a means by which He would want His people to repent and return to Him. (Dt 28:12, 23-24)
Yet God has promised since the Flood that as long as this Earth remains, there would still be the four seasons (Gen 8:22). And He has further promised that as long as He is in control of our unique solar system within His universe, and that the size of the universe can not be determined, Israel would remain a nation before Him, and His covenants with David and with the Levites would not be broken (Jer 31:33-37; 33:19-26).
So we can be assured that Yeshua is going to return at the appointed time to regenerate this Creation and make the Earth a very habitable place during His reign! (Ps 96; Mt 24:32-39; Rom 8:18-25)
