The reading is from St. Paul's Second Letter to the Corinthians 5:1-10

Brethren, we know that if the earthly tent we live in is destroyed, we have a building from God, a house not made with hands, eternal in the heavens. Here indeed we groan, and long to put on our heavenly dwelling, so that by putting it on we may not be found naked. For while we are still in this tent, we sigh with anxiety; not that we would be unclothed, but that we would be further clothed, so that what is mortal may be swallowed up by life. He who has prepared us for this very thing is God, who has given us the Spirit as a guarantee.

So we are always of good courage; we know that while we are at home in the body we are away from the Lord, for we walk by faith, not by sight. We are of good courage, and we would rather be away from the body and at home with the Lord. So whether we are at home or away, we make it our aim to please him. For we must all appear before the judgment seat of Christ.
