"And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be" (Zechariah 14:8).
It is interesting that there is no mention of either spring or fall, as such, anywhere in the Bible, though there are several references to summer and winter. Today's date happens to be the date of the vernal equinox and is generally considered to be when spring begins in the northern hemisphere, although there is apparently no formal calendric period of either spring or autumn, and the culturally accepted periods vary from country to country.
In any case, we do know that there have been so-called "seasons" from the very beginning, owing to the earth's axial tilt. Speaking of the sun, moon, and stars when He created them, God said to "let them be for signs, and for seasons, and for days, and years" (Genesis 1:14).
Furthermore, although the great Flood produced drastic changes in the earth, it did not change the seasons. God told Noah: "While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease" (Genesis 8:22).
There are tremendous changes yet to take place in the earth during the time when Christ returns, as described in the prophetical books. Once again, however, as our text indicates, there will still be summer and winter--and therefore, also spring and fall. "Thou hast made summer and winter" (Psalm 74:17) and apparently so it will always be.
Even in the new earth, the wonderful tree of life will "bare twelve manner of fruits, and |yield| her fruit every month" (Revelation 22:2). Different fruits for different months at least implies different seasons. "Whatsoever God doeth, it shall be for ever" (Ecclesiastes 3:14). HMM
