Ryrie addresses the permanence of the Spirit’s indwelling:
“. . . sin affects the ministry of the Spirit to the believer, not His presence within the believer. Sin grieves the Spirit (Ephesians 4:30) and causes the ramifications of His indwelling, but not the fact of it, to be diminished. It is the filling of the Spirit . . . , not the indwelling of the Spirit that is affected by sin.”
