Pete Greig who leads a worldwide 24-7 prayer movement among college students, has a great article on their blog. His tag phrase is, "100% right!... but only partly". I think this phrase touches a useful thought on the disciple's approach to "our way of following Jesus" in a diverse World-Christian community. And the phrase also has great value for talking to unchurched and dechurched people about Jesus.
In a related vein, Simon Barrow, columnist for the Telegraph in the U.K. has a valuable defintion of faith in his recent column about Richard Dawkins' Atheist busboard advertisements:
It seems that what Pete is saying--hold onto your way with tenacious grace knowing that your knowledge is not complete and God loves diversity and what Simon is saying--faith is not a blind leap but a reasoned grasp of God's mystery and revelation, are both valuable perspectives for people loving, following and serving Jesus in this generation.
