This book is instructional guide on to become complete in the family of God. It also presents the true gospel as Jesus explained to Nicodemus. This book summarizes Jesus's explanation to all living men about the creation of God and emphasizes not only the importance of being born into the world but also the greater importance of being reborn into the family of Jesus Christ. As a reminder, I would like you to know that the true gospel of Christ teaches men how to inherit the kingdom of God. Jesus was elucidating the true gospel of the kingdom to Nicodemus without omitting anything. In John 3:3, He said, "You must be born again, spiritually born of water and fire, to inherit the kingdom." Therefore, the three steps that Jesus gave to Nicodemus are as follows: 1. You must repent. 2. You must be baptized in water and fire. 3. You must receive the Holy Spirit of God. These are the three steps you must take to become part of the family of God. Without these three steps, if you call yourself a Christian but have not taken them, you are not there yet. These are the required steps to be called a Christian. Jesus did not suggest other steps. He did not ask you to buy a plane ticket. All He asked for are these three steps. This is the gospel of the kingdom according to Jesus Christ, our Lord, which needs to be followed to be part of the family of God
