To me a Christian is either a man who lives in Christ or a phony. You Christians do not appreciate that it is on this - the almost external testimony that you give of God - that we judge you. You ought to radiate Christ. Your faith ought to flow out to us like a river of life. You ought to infect us with a love for him. It is then that God who was impossible becomes possible for the atheist and for those of us whose faith is wavering. We cannot help being struck, upset, and confused by a Christian who is truly Christlike. And we do not forgive him when he fails to be.
