"I keep on speaking the language of the Christian faith because, although the words themselves may well be mostly dead, the longer I use them, the more convinced I become that the realities that the words point to are very real and un-dead, and because I do not happen to know any other language that for me points to these realities so well." (Frederick Buechner)
For the unbeliever, words like redemption or salvation are either flat and lifeless or, worst, have some negative connotation, as in intolerance or self-righteousness. Yet for the believer, these words are round, having depth and breath, like a well that never ceases giving water. At times they are flat to me too; other times they rise up on the page and shout at me and then I think that the realities to which they point are ones you can never really fully explore.
