Among the numerous phenomena of our solar system is the constant revolution of the earth around the sun. Its revolution has a fixed orbit and is completed in one year. Due to the elliptical shape of its orbit and the sun not being at its exact centre, the different seasons occur. Besides its revolution, the earth rotates on its axis and this is completed in twenty-four hours. This rotation is the cause of day and night. In the vastness of space, the revolution and rotation of the earth with extreme precision and their being greatly subservient to human beings’ interests, are the most wonderful of happenings. One who ponders over these blessings will be overwhelmed with feelings of gratitude to God.
