In Eric Bryant's new book on faith and diversity Not Like Me, he writes:
 

Not Like Me by Eric BryantThe most effective apologetic is love. This may seem simplistic or even naive in a pluralistic, universalistic, spiritually heightened, anti-Christian, and syncretistic world, but knowing all the "right" answers is not nearly as effective as demonstrating a transformed life of genuine love and concern and care.

We need to follow the apostle Paul's guidance to "preach the word; be prepared in season and out of season; correct, rebuke and encourage," while ensuring that we follow how he wanted his church-planting protege, Timothy, to do this -- "with great patience and careful instruction" (2 Timothy 4:2).

Is this true?

Is the most effective way we can demonstrate a belief system not through what we say, but what we do?

If so, what are the implications for how Christians should and should not act, as it relates to sharing their faith?
