What does 2 Corinthians 5:3 mean?

The previous chapter concluded with Paul's statement of confidence that he would be resurrected, as Christ was, after his death in this life. Once in eternity, his experience of the glory of God would far outweigh and outlast any amount of suffering in this life.

Paul has acknowledged, though, that suffering on this side of eternity is real. As temporary as this life is, it is marked by what he calls a "groaning:" a longing to exist in our permanent, heavenly dwelling. He has compared living in our current bodies in this life to living in a tent. The shelter provided is valuable but incomplete. In the next life we will live in a permanent house, he has said.

He longs for this moment since he is convinced that he will not be "found naked." That is, Paul knows that leaving behind the tent of our current, sin-ravaged bodies will not leave those who are in Christ without a body. Instead, we will be found in the bodies we have always been destined for. Paul wrote at length to the Corinthians about the resurrection of the believers and the resurrection body in 1 Corinthians 15.
