<p>5:11- see on :1.</p><p><i>Therefore, encourage one another and build each other up, even as you already do</i>- As explained on :8 and :9, we should encourage each other with the fact that if the Lord returns right now, we really shall be saved. And we must ask how often we specifically state this to each other. As noted on 4:18, this ability to build each other up was a sign of maturity, rather than relying upon visits and letters to encourage them. The words for 'encourage' and 'build up' are also found in the record of how these things are done to believers by the Holy Spirit (Acts 9:31). But that Spirit power is partly mediated to the members of the body of Christ through the other members (Eph. 4:16); our efforts to build each other up are a channel for the Spirit, and will be blessed. </p>
