A Christian Science perspective.
At the slightest sniffle or sign of my not feeling well when I was a little girl, my dad would ask me, "Under the weather?" This question always perplexed me; I simply didn't understand what it meant. After my dad joined my mother in the study of Christian Science, this phrase evaporated from our home. This came about naturally from what my dad was beginning to understand: God's creation is under God's loving care and not susceptible to changes in weather conditions.
It is, however, a strongly held belief that all of us are, in fact, under the weather, that is, under the influence of atmospheric changes, and that shifts in climate can affect our health and happiness.
In a very succinct phrase, the Bible puts the beliefs of seasonal misery out of business. Speaking of God, the Psalmist writes, "Thou hast made summer and winter" (74:17). I have loved considering the correction this short and powerful declaration makes whenever I hear advertisements for seasonal remedies as well as when I've prayed for myself and others seeking healing from these kinds of afflictions.
God is the source and maintainer of all good. The first chapter of Genesis states, "And God saw every thing that he had made, and, behold, it was very good." In the verse from Psalms, the ideas of summer and winter are attributed to God as Creator, and therefore they are good. The effect of them is good. They are pleasant manifestations of His nature, filled with infinite variety and beauty.
I've reasoned that shifting seasons is a little like shifting a view or perspective. Take, for instance, a beautiful piece of sculpture. You can stand in front of it and observe its lines and lovely articulation, and then, move around to the sides and back, and see it from other angles, still enjoying the same piece. The different views do not change the sense of awe and appreciation of the inspired work.
