The earth is not isolated from the rest of creation; it is inseparably bound with the cosmos. The existence of life on the earth and its flourishing and growth are possible only when it maintains total harmony with the rest of the universe. This balanced and harmonious interaction between the earth and the sky proves that the control of the earth and the sky rests in the hands of one single Being. Had it been with two beings, there would certainly have been frequent clashes between them and consequently the preservation of the existing life on earth would not have been possible. The universe with all its immense majesty and meaningfulness projects the image of its Creator as a God who is absolutely above all shortcomings. To assume the Creator of all things to be a Being subject to shortcomings and weaknesses would be to grossly undervalue the existing universe.
