The purpose of this paper is to present the concept of the Manifestation of God as it is developed through the Sacred Writings of the main religions of the world.
The powerful impact on civilization of Christ, Moses, the Buddha, or Muhammad can be seen both in the collective development of humanity and in the life of every individual.
This concept it is analysed by introducing the proofs and the purpose of their mission, their sufferings and denial, which are the central themes of the paper. The lives of the Manifestations of God is always questioned before they are fully accepted by humanity in general. Another important aspect that is developed in the paper regards the threefold reality of these Luminous Beings: material, human and divine. In the Bahá'í Writings it is explained that the beginning of all things is the knowledge of God and this can be obtainedthrough the manifestation of God. To try to comprehend this is very important in one spiritual search. The last section of this paper is about the relationship of the Manifestations with the Essence of God, and the relations between themselves.
