A personal god is a deity that relates and can be related to as a person. The personhood of God is one of the characteristic features of monotheism . In the sacred scriptures of Judaism, Islam and Christianity, God is conceived and described as being a personal creator, with a purpose for the creation. In the Pentateuch, for example, God talks and instructs his prophets and is conceived as possessing volition, emotions (such as anger, grief and jealousy), intention, and other attributes characteristic of a human person. Personal relationships with God may be described in the same ways as human relationships, such as a Father, as in Christianity, or a Friend as in Sufism. In Vaishnavism the reality of God is always not in an idealization, but the actual impact of God in the life of man.
