The aim of our study is to dive deep as much as possible into the concept and realities of the Kingdom of God and the perspectives for Humankind.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 importance of the kingdom of God 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 the kingdom of God is the origin and the true home of humankind. Though we live in a material world, our final destination is a spiritual one whose entry depends on our behaviour or conduct on Earth. It can either be hell, negative for us if we live far away from divine principe or it can be Heaven, good in the kingdom of God that is founded on righteousness, justice, mercy and truth. We should therefore live according to God’s exclusive will by praying and working hard for the advancement of the Kingdom of God.
