Due to God’s design, the seasons cause changes in temperature, light, and length of day which results in soil changes, plant life changes, and the hours of man’s labor, etc. It reasonably follows that man in seeking to live within God’s design would naturally eat the foods that are in season for the particular area he is living in — as well as work and rest according to the season. By design plants, animals, humans, and the weather work synergistically together to produce the greatest benefit for all.
