I just read a great article at Relevant called "Frangrant Witness," which contrasts the unfortunate stereotype of evangelicals who are more concerned about doing (witnessing, the adjective) as opposed to being (a witness, the noun).

The author references the contrast from a Pauline epistle:

How does Paul contrast Christians with religious salesmen? In the same passage, he says that God “uses us to spread the aroma of the knowledge of him everywhere. For we are to God the pleasing aroma of Christ among those who are being saved and those who are perishing” (2 Corinthians 2:14-15). God does the work of conversion, not by dispensing us like a million Amway distributors, but by loving us so much that we can’t help loving everybody else. That love is like sunshine washing into the souls of all we meet.

Frankly, and apart from our evangelistic techniques, the way we treat some of our brothers and sisters of faith just plain stinks, as well. (Read some of the comments on the most hotly contested posts here at TC, for example.)

Some folks rightly suggest that we should listen more than speak. I contend that we should sniff more than speak, as well.
