Testimonies?

In normal English usage "testimony" refers to a factual recounting of a real event which an eyewitness experienced.  Maybe it is a traffic accident, maybe war crimes.
(Not a "testimonial" which has a commercial connotation associated with an endorsement of a product by its user)

In evangelical/fundamentalist Christian subcultures of Canada "testimony" bears an additional sense of a personal account of how God-in-Christ intervened miraculously or providentially in the speaker's life somehow.  Often it is limited specifically to the process of how a person initially turned from an unbeliever to a believer, or was "saved".  (In many "charismatic" (in the theological sense) churches one may "testify" at many, if not most, religious meetings, and this "testimony" may be about some more recent event in the believer's life which they interpret as being an instance of God's intervention in their personal life and of their (eventual) positively evaluated response to God.) 

I have witnessed middle-aged to elderly people attending a meeting invited to stand and spontaneously give a "testimony".   I remember several times being struck and fascinated by vivid detailed glimpses into of regular people's personal life events situated 30 or 40 years in the past, the minute details still sharp from repeated retellings over the decades.  And I recall thinking "but what has God done in your life recently?"

Now, language and consciousness are indivisible aspects of being human.  Our human awareness and experience of existence is impossible without numerical, lexical, logical and grammatical polarities such as "I/you",  and "body/thing", and "this/that" and "one/two".  On the other hand the very concepts of "body/mind", "language/awareness"  or  "speaking/acting",  while on the one hand help us think and improve our experience and use of these "things" (for love, mercy and justice), at the same time this codification sets up an unreal split or division between them.  I would like to say "Speaking and acting are indivisible" but this statement self-destructs because it is equal to saying "two things are one thing" which is not currently logical in English.

Nevertheless, I believe action speaks and speech acts.  Therefore, the Christian "testimony" consists of more than a story told in words: it is also actions and attitudes.  How we act towards and treat our family, neighbours, acquaintances, school mates, work colleagues, other drivers on the road and people we don't particularly like, speaks volumes.  But we have known this since kindergarten, when we heard it said: "Actions speak louder than words".  So testify to your world about your current love affair with God-in-Christ through your whole life, today.
