The Holy Ghost Who Dwells in Us. by W. H. Westcott. 2 Timothy 1:14, Conclusion

The Holy Spirit occupies a very special place in relation to Christians, distinct from anything set forth in Old Testament times or enjoyed by Old Testament saints; distinct from what was enjoyed by the disciples who companied with the Lord previous to His death, resurrection, and ascension; and distinct from what will be wrought in men (Israelites and Gentiles) after Christians are gone from the earth to the Lord; when the time will have come for the millennial reign of Christ, and its attendant glory and blessing.

We will reverently speak of His unique service in Christianity and invite the reader's prayerful study and exercise of heart over the Scripture; that we may seek to answer to the grace that God has shown to us and to the position Christ has won for us, loyally and largely, till He comes.
