Jack was the name C.S. Lewis preferred that his friends call him. Here is a quote from Lewis that has become my favorite non-scripture quote. I think it is appropriate as we consider the walls we build and maintain, and as we consider our job of evangelism in general.
“It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest and most uninteresting person you talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree, helping each other to one or other of these destinations. It is in light of these overwhelming possibilities, it is with the awe and the circumspection proper to them, that we should conduct all our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal.
– C.S. Lewis, The Weight of Glory
And here is what we come away with: every contact you have with other people can and does influence their eternal destiny. All you have to do as a Christian to send someone to hell is make sure you give Christians in general a bad name so that that person never seeks out Christ for salvation. Treat them poorly or impatiently, ignore them, alienate them, or hurt them, and you are pushing them toward hell. Treat them with kindness, love, patience, sincerity, gentleness, respect, and mercy, and you lead them toward heaven.
Think about that the next time the new cashier is taking too long to find the buttons on the register while taking your order…your impatience could be moving them one step closer to eternal separation from God, but a smile might be all that God needs to open their heart to the gospel.
