No, God has not created any religion. God is one. He is neither Hindu nor Muslim nor Christian. The Vedic injunction is ekam brahma dvitiyam nasti: God is one; He cannot be two. So whether you are Hindu, Muslim, or Christian, God is one. Religion does not mean stamping oneself as a Hindu, a Muslim, or a Christian. No, religion means to know God is great and that we are subordinate to Him and maintained by Him. According to Caitanya Mahaprabhu jivera ‘svarupa’ haya-krsnera ‘nitya-dasa’: [Cc. Madhya 20.108] Every living being is an eternal servant of God. This is religion. If anyone simply knows these things – that God is great and we are subordinate, and that our duty is to abide by the orders of God – he is religious.
Sometimes the Personality of Godhead Himself descends and teaches transcendental knowledge; at other times He deputes His confidential servants to perform this act of kindness. All the messiahs – saints who have come before or who will come in the future to preach the transcendental message of the kingdom of Godhead – are to be understood as the most confidential servants of the Personality of Godhead. Lord Jesus Christ appeared as the son of Godhead, Muhammad introduced himself as the servant of Godhead, and Lord Caitanya presented himself as the devotee of Godhead. But whatever their identity may be, all such messiahs were of the same opinion about one thing: there can be no permanent peace and prosperity in this mortal world. All of them agree that we have to go to a separate world, where peace and prosperity have their real being. We have to search out our eternal peace and prosperity in the kingdom of God, which is beyond this mortal world.
