God created man, and then He created Paradise and Hell. Man was later settled on the earth. Here man has freedom to do as he wishes. But this freedom is not forever. It is temporary and meant for his trial. It is so that good and bad may be distinguished from one another. God is watching those who, despite being granted freedom, can adopt realistic attitudes, and surrender themselves to the will of God, and who are the people who misuse their freedom and prove themselves to be rebels. Both kinds of people have been mixed in this world. Both have equal opportunity to gain fully from the blessings of God. But, after the completion of the appointed time of trial, those groups will be separated from one another. The first group will be lodged in the Gardens of Paradise forever, while the second group will be consigned to Hell for all eternity. This plan devised by God for human existence put man in an extremely delicate situation, for the outcome of his brief stay in this world was going to appear in one of two extreme forms—either eternal comfort or eternal chastisement. That is why, besides other natural arrangements for divine guidance, God also arranged to send to mankind His messengers and His Scriptures, so that no one should remain unaware of the reality of life. No one may then attempt to excuse his misconduct on the plea that he was not informed of the divine plan of how human beings were expected to lead their lives. From start to finish, this divine plan necessitated all of the prophets bringing the same message and the same mission to mankind. For, when all human beings without exception are to be weighed in the divine scale, how could their ‘test papers’ be different from one another? The truth is that the message brought by all the prophets was one and the same and they communicated that same message to all human beings: that everyone is standing at a perilous watershed. On one side of it is Paradise and on the other is Hell. If one steps to one side, one will reach Paradise; if one steps to the other, one will fall into the gorge of Hell. All the prophets had this identical message.
