The reason for a man going astray in this world is that here he has complete freedom to reject the Truth. He even has the opportunity to give fine justifications for erroneous thoughts, words and deeds. Man enjoys full freedom in this world of trial to accept or reject the Truth as he pleases. If the preacher of God’s word appears in the shape of an ordinary man, the ‘reason’ given for ignoring him could be that his effectiveness hinges on a talent for leadership and has nothing to do with Truth or righteousness. Similarly, if a book complete in every detail, comes down from the sky, he will say, ‘This is mere magic,’ to justify his rejection of it. The people of Makkah used to ask, if the Prophet was appointed to convey God’s message, why God’s angels were not with him to testify. A man talks like this because he is not serious about the call of God’s message. If he is serious, he will immediately come to know that this world is a place of trial. The test can be carried out only when realities are hidden behind a curtain. If the hidden realities were revealed and God and His angels made their appearance, there would be no question of prophethood or of giving the call of Truth, because thereafter nobody would dare to deny the realities. In the present world, because of their devotion to externals, people are unable to recognise the Messenger of God from the importance of his message. God’s Messenger appears to them like an ordinary man suddenly emerging and claiming very high status. They assess him on the basis of his outward appearance and, finding him insignificant in that respect, they deny him.
