V.1 We know that when we leave this world we have a house not made with hands, eternal in the heavens. If the believer dies, his earthly house (body) later will be changed into a body fit for heaven. Notice 3 conditions mentioned here in these first 4 verses. “Unclothed” the condition of a believer who has passed away and is with Christ, but has not yet received his new glorified body. “Naked” the condition of a lost one who does not have the robe of righteousness and stands guilty and naked before God. “Clothed upon”, that glorious condition when all the Lord’s redeemed ones will have their new bodies. This will take place the moment the Lord comes in the air to take us to heaven.
V.6-8 Paul is always perfectly confident, and not only Paul, for he says “we are ... ”
V.9 Because of this confidence (trust) we ought to love to please the Lord.
V.10 Every believer in our Lord Jesus, will have his life reviewed and he shall find that everything done for our Lord in obedience to His Word will be rewarded.
V.20 We can be like ambassadors who represent our Lord in this guilty world — only the Apostles were really “ambassadors.”
