The aim of this paper is to explore the nature of God as the supreme being of the universe and the source of every existing things and beings. To achieve that goal, the methodology used is based on critical literature review, phenomenology and Biblical methodology which is a method that seeks to shed light upon the historical processes which give rise to the biblical texts. It proceeds from textual criticism to redaction criticism, operating with the help of scientific criteria. The objective of our study is to answer a number of questions useful to shed more light on the understanding of God’s nature, His features, His will and the impact of knowing Him on the physical, psychological and spiritual lives of people and ultimately to spread the gospel of Jesus Christ. The interest of this work is spiritual, philosophical and social. The results of our analysis show that Knowing God helps us with a better understanding of our own identity. Before we can appreciate who we are, we need to know who made us and why we are here on. Identifying God is a herculean task as there seems to be various gods as we are living in a polytheist environment. Based on the Bible God is three in one (Adonai) that is the Father (Yahweh), the son (Christ Jesus) and the Holy Ghost (Spirit of God in action). He is the maker, king and master of the cosmos, of the universe, the truth, the light, the right path.
