Moreover, a dialogical posture is one that listens as well as shares. Faith in God is open to truth wherever it is encountered; it takes both the questions raised and the answers given by unbelievers extremely seriously. To put all this another way, authentic Christian faith, as I understand it, has nothing to fear from interchange with those of differing points of view. One must have confidence that God’s truth will vindicate itself to those who seek it sincerely; it does not need to be defended. A faith based in fear is like a faith without works; it is not faith at all.
