When God created man, He did so to dwell in him and to reflect His glory. From the Old Testament, we see how the Father sent His angel and the Holy Spirit to rest upon certain people, showing that there was a divine plan and desire: to gather everything back under His love.
In the fullness of time, Jesus came, God made man, to incarnate and present in Him a new humanity that depended entirely on the Father.
Today we are also called to be a dwelling to contain all His glory and to allow Him to express Himself through us. You are no longer alone. He dwells in you. I encourage you to discover this in the intimacy of reading this book.
