According to Bill Johnson in "When Heaven Invades Earth," the coming of Christ was not solely about salvation; it served as a crucial step towards a greater purpose. Redemption was essential to ensure that humanity could have a relationship with God, but it was merely the starting point. The ultimate aim was for believers to experience the fullness of the Holy Spirit, enabling them to live a life overflowing with God's presence.

Johnson emphasizes that God's desire is to fill each individual who is born again with His Spirit so that they can embody His fullness. This transformative experience allows believers to engage in miraculous living and fully partake in the divine nature. The focus on being filled with the Holy Spirit reflects the profound aspiration for believers to not only receive salvation but to live in a continual, empowered relationship with God.
