for a witness
John 1:7
1:7 for a witness. The gospel of John is uniquely designed to bear “witness” to the deity and saving work of Christ. This verse has the first of forty-seven uses of this word or its derivatives (“record,” “testimony,” etc.) all from the Greek marturia in John’s gospel, as well as seventeen times in his three epistles and sixteen times in Revelation—far more than by any other Biblical writer.
