Let me ask you a question right away: do you have a testimony? A testimony is usually a verbal expression or acknowledgment as a witness under oath in response to interrogation by a lawyer or by an authorized public official. When we see the word testimony used, we can go to
And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death (Rev 12:11). Usually, the word ‘testimony’ is used for the law of God as given by God to Moses on Mt. Sinai.

But we are called to share our story (i.e., our testimony) to those who do not believe in Jesus—or whom the Bible calls ‘lost.’ In fact, John Kramp wrote a very compelling book called, “Out of their Faces and Into Their Shoes.” In this book, he coined a study called lostology. This is the study of being lost and what the experience can teach Christians about evangelism. The fact is, as time goes on, few Christians understand non-Christians. Sadly, many of us (yes, ‘us’—myself included) have an insider’s mentality.

Reading news outlets and listening to songs on the radio can tell us a lot about what’s happening, there are two things that you should always carry, no matter where you find yourself: the story of the gospel, and the story of how the gospel changed you.

We speak of your sphere of influence: your friends, relatives, co-workers, neighbors. Likely if you’re in that realm, you know and share many of the same mindsets. But you have His story and your story of how His story changed you. We don’t like the word change, do we? But if we are Christians, our life counts on Jesus changing us from death to life, from darkness to light, from lost to found.

The three components of your personal testimony are:

1. Tell someone where you were before Christ changed you.
2. Tell someone when Christ changed you.
3. Tell someone how Christ changed your life from then on.

Acts 22:3-21 is a beautiful outline of what a testimony is about. Listen here.
