John Piper, Rethinking Retirement : Finishing Life for the Glory of Christ, Crossway Books, 2008.
Finishing life to the glory of Christ means resolutely resisting the typical American dream of retirement. It means being so satisfied with all that God promises to be for us in Christ that we are set free from the cravings that create so much emptiness and uselessness in retirement. Instead, knowing that we have an infinitely satisfying and everlasting inheritance in God just over the horizon of life makes us zealous in our few remaining years here to spend ourselves in the sacrifices of love, not the accumulation of comforts.
