A woman stands before judge and jury, one hand on the Bible, the other in the air, and makes a pledge: to tell the truth, the whole truth, and nothing but the truth. She’s a witness. Her job is to tell the truth.
The Christian, too, is a witness. We, too, make a pledge to tell the truth. The bench may be absent, the judge unseen, but the Bible is present, the watching world the jury, and we’re the primary witnesses—subpoenaed by no less than Jesus himself in Acts 1:8. “You will be my witnesses, in all of Judea, in Samaria, and in every part of the world.”
The witness in court eventually steps down from the witness chair, but the witness for Christ never does. The claims of Christ are always on trial, and we remain under oath!
