D.A. Carson: “[R]estlessness is for our good. It is a design feature of our makeup, of our nature as creatures made in the image of God. We were made to inhabit eternity; by constitution we know that we belong to something better than a world (however beautiful at times) awash in sin. Paul understands this point perfectly (2 Corinthians 5:1 – 5). He anticipates the time when “the earthly tent” (our present body will be destroyed, and we will receive “an eternal house in heaven, not built by human hands” (5:1) — our resurrection body. “Meanwhile we groan, longing to be clothed with our heavenly dwelling” (5:2). It is not that we wish to “shuffle off our mortal coil” and exist in naked immortality: that is not our ultimate hope, for “we do not wish to be unclothed but to be clothed with our heavenly dwelling, so that what is mortal may be swallowed up by life” (5:4). Then Paul adds: “Now it is God who has made us for this very purpose and has given us the Spirit as a deposit, guaranteeing what is to come” (5:5). God made us for this purpose, i.e., for the purpose of resurrection life, secured for us by the death of his Son. Moreover, in anticipation of this glorious consummation of life, already God has given us his Spirit as a deposit, a kind of down payment on the ultimate inheritance. Small wonder, then, that we groan in anticipation and find our souls restless in this temporary abode that is under sentence of death.
