This is such an inspiring verse that lets us know that we have God's promise of the seasons. As long as the earth endures, then all the seasons shall endure. The heat of summer burns fierce, yet we know it is only for a time. The days grow shorter and cooler and fall is ushered in amongst wondrous colors of leaves. The leaves abandon their branches and drift to the ground, soon the first snow falls. Through the cold and winter, we long for the first rays of the Spring sun on our faces. Just in time, the glorious beauty of Spring returns. Flowers begin to bloom, birds begin to sing and trees begin to bud. A promise once again is fulfilled. As long as the earth endures, God will always keep His promises.
