Man-made workshops, or factories, are not capable of making a machine which can start giving birth to similar countless machines. Our factories have to manufacture such machines one after another. But in the workshop of God, such an event takes place every day. The seed of a tree is sown and then generations of trees go on multiplying out of that simple, original seed. This is the case with human beings also. Starting with a man and a woman, billions and billions of human beings have started coming into existence—and there is no end to this process. This observation shows that the power of God, who created the universe, is limitless. He is capable of this rare feat of creation by which, primarily, one entity is brought into existence and thereafter it continuously replicates itself in countless numbers. Similarly, God can create a great and perfect world out of this present world. The concept of the Hereafter is not a far-fetched theory; belief in it amounts to acceptance of the possible occurrence of certain future events on the strength of the present observation of similar events taking place every day.
