Hazrat Mirza Nasir Ahmad(rta) – Khalifatul-Masih III (the third successor of The Promised Messiah), in the capacity of Khalifatul-Masih, on his first visit to some countries of Europe and Africa delivered a public lecture on 28 July 1967 at the Wandsworth Town Hall, London. It was later published under the title A Message of Peace and a Word of Warning and is being presented here again. In this lecture Huzoor introduces the Founder of the Ahmadiyya Muslim Community and the Movement itself and after mentioning the purpose of coming of the Promised Messiah(as), he concludes his lecture with the wording of The Promised Messiah(as) "O Europe, you are not safe and O Asia, you too, are not immune. And O dwellers of Islands, no false gods shall come to your rescue. I see cities fall and settlements laid waste. The One and the Only God kept silent for long. Heinous deeds were done before His eyes and He said nothing. But now He shall reveal His face in majesty and awe. Let him who has ears hear that the time is not far. I have done my best to bring all under the protection of God, but it was destined that what was written should come to pass. Truly do I say, that the turn of this land, too, is approaching fast. The times of Noah shall reappear before your eyes and your own eyes will be witnesses to the calamity that overtook the cities of Lot. But God is slow in His wrath. Repent that you may be shown mercy! He who does not fear Him is dead not alive."

In a world plagued with intolerance for cultural, racial and religious differences, A Message of Peace serves as a panacea to the ills of the society. Prophetic in foresight and universal in scope, this book lays out a path to the peaceful existence of all humans based on the central theme of worshipping the One God. It is not surprising therefore that A Message of Peace forms the last work of a man who was destined to lay the foundation for the establishment of peace in this day and age and whose advent was prophesied in all major religions of the world-the Promised Messiah and Reformer of the Latter Days. "My countrymen!" writes the Promised Messiah, "A religion which does not inculcate universal compassion is no religion at all. Similarly a human being without the faculty of compassion is no human at all."
