Adam Clarke's Commentary on the Bible

Verse 11 (Romans 8:11)

But if the Spirit, etc. - This verse confirms the sense given to the preceding. He who here receives the grace and Spirit of Christ, and continues to live under its influence a life of obedience to the Divine will, shall have a resurrection to eternal life; and the resurrection of Christ shall be the pattern after which they shall be raised.

By his Spirit that dwelleth in you - Instead of δια του ενοικουντος αυτου πνευματος , because of the Spirit of him who dwelleth in you, DEFG, a great many others, with the Vulgate, Itala, and several of the fathers, have δια το ενοικουν αυτου πνευμα , which gives almost no variety of meaning. The latter may be neater Greek, but it is not better sense than the preceding.
