I (Jesus) will pray the Father, and He shall give you another Comforter - Holy Spirit - so that He may be with you forever, (…) for He dwells with you and shall be in you (John 14:16-17) The purpose of this book is to shorten the distance between Christians and the Holy Spirit in His true role that is to be near and inside Christians. If the Lord Jesus Christ has promised a Holy Spirit who will be eternally with the Christians, near and insude them, there is much to know about this Comforter. It is what this book proposes through five essential truths underlined in the Scriptures: Born of the Spirit, Live in the Spirit, Walk in the Spirit, Pray in the Spirit and Free in the Spirit.
