Did I mention that I like what Len has to say?
The best apology is a life lived in the grace of Christ. But unless that life has a strong relational dimension, it remains private.. love is relational by definition. We must demonstrate in renewed communities that the Gospel is true. Today the greatest hindrance to the Gospel is faith communities that are not transformed communities or are based almost solely on Sunday relationships.
St. Francis wrote, "Preach the gospel at all times. If necessary, use words." The witness to the power of the early church was not just the signs done by the apostles but the surrounding community looking on and saying, "See how they love one another!" The Spirit makes us One. When those around SEE the truth in flesh, they will believe it. Isn't this the very heart of the meaning of the incarnation? God could have lectured us as to His caring for us, His presence with us.. instead, He demonstrated love in his life by living among us, and by dying for us.
