The Characteristics of an Effective Testimony
A. Personal and Interesting
In order to be effective, a personal testimony must be, in fact, personal. 
It cannot come out of a can, or some kind of generally prepared book or other 
source. It must be "your" story, not the story of someone else. Folks 
will want to know what all this means to you, and what effect it has had on 
you, and your life. Remember that you have, in your possession, the greatest 
gift ever given, to anybody. Keep that in mind as you tell your 
"story." Bored hearers are soon lost. Humans have short attention 
spans, unless you are able to bring them along with you.
B. Clear, Concise, and Complete
A second requirement for effectiveness is that your personal testimony must 
be clear,  concise, and complete. You must be able to convey the essential 
information in a comparatively brief amount of time, with little superfluous 
information. Superfluous information will tend to muddy the water and distract 
your hearer. Essentially, you need to be able to get to the point, without 
meandering, rambling or drifting. This is also essential at the time of 
delivery, in that you will need to be able to keep the conversation on course. 
If your testimony is effective, you will likely have later opportunities to 
share all kinds of things from your "life" testimonies, but do save 
them for later.
Next, you must be able to share your testimony in a language and manner that 
the hearer can readily understand. Christianese (religious jargon) should be 
eliminated as much as possible. Where it cannot be eliminated, terms must be 
defined, so understanding will be conveyed. You must meet your hearer where he 
or she is. They will likely be unwilling to come to where you are. 
C. Conclusive
Next, your personal testimony must be conclusive. Sometimes, you will be 
sharing your testimony with fellow believers. They will want to know if, in 
fact, you are a fellow believer. Your understanding, acceptance, and conveyance 
of the Good News of Messiah must be clear and complete, or your fellows will 
not otherwise know what to make of you. This is especially true if you are 
seeking membership in a congregation. The leadership will want to know if you 
qualify for that membership.
D. Consistent and Credible
Sometimes, your personal testimony will need to be delivered in different 
parts, at different times, rather than all in one sitting. This is fine, as 
long as context can be retained, and all elements have been included once you 
have finished. In this way, your hearer will "accumulate" your 
personal testimony as your relationship develops.
You must always, first let the hearer know "who's" you are, so 
they will have the context necessary to interpret what they see and hear in 
you. My mentor put it this way, "When you enter a room for the first time, 
come in singing the song -- with the words. Thereafter, whenever you 
enter the room, hum the tune, when they hear the tune, they will remember the 
words." This means, let your hearers/observers know who's you are, and 
they will then know where your words and deeds are coming from.
Trust me. You will be carefully observed. Remember, your life and responses 
to it, are part of your testimony. Make sure that your life lines up with your 
words, or you will be dismissed, due to a lack of credibility.
E. Impeccably Honest
While it is very important to us, and to the Holy One, for those we care for 
to receive the gift that we have received, we must make certain that the Holy 
One can bless what we are saying and doing. The ends never justify the means is 
this regard. There must never be any hint of embellishment or deceit in our 
personal testimony. The consequences could be disastrous.
F. A Privilege Granted
Finally, remember that the opportunity to share your personal testimony is a 
privilege that you "earn." It is not a right. Your hearer must grant 
a hearing. You cannot effectively force that hearing. Ears that are closed, 
will not receive what is pressed upon them. Also, a question asked is not a 
request for the recitation of "War and Peace." Answer the question, 
clearly and concisely. Do not try to fill an extended shot glass with a fire 
hose. Be sensitive to your hearer, and to the Divine Presence within.
