In every period, the majority of people have admitted, that the Creator and Lord of the Universe is God, and that it is He who has provided them with the wherewithal for the sustenance of life. To bring the Universe into existence and to make every provision for life on the earth are such gigantic tasks that it is impossible to attribute their undertaking to anyone except the one and only God. This assertion calls for man to devote his attention to God above all; his life should be a God-oriented life. But man sets himself other goals; he places entities other than God at the centre of his attention. Almighty God has revealed the realities through His prophets. In addition to that, He has created the world in such a way that it has become the practical illustration, or analogy of hidden realities. For instance, it is a fact that human beings will be resurrected after death—a fact shown at the level of vegetation again and again. It is seen by man every year that the land becomes dry and dead. Then there are rains and the land is again covered with lush greenery. This phenomenon points to the fact that man will be brought to life again after death. Another special feature of the present world is that it is most wonderfully favourable to human existence. Everything here has been created in such a way that it can be used by man for his own purposes as he wishes. This blessing demands that a feeling of gratitude should develop in man. Whenever he happens to use anything in God’s world, he should spontaneously bow his head before God and words of acknowledgement and prayer should fall from his lips.
