The Holy Spirit A B Simpson Chapter 9 – Filled with the Spirit It is one thing to be baptized into the one body by the Spirit; it is another thing to drink into that one Spirit. The first is an act; the second is a habit. The first brings us into a relationship; the second is the true use of that relationship, the drinking of His fullness until we become filled, and the habit of abiding in His fullness so that we are always filled.
