What does he mean, ‘by the word of truth’? Our minds may go readily to the idea that this is his way of describing the whole Bible and all the doctrines of the Scripture. But actually when the apostle Paul uses this term he is speaking particularly about the gospel.
On one occasion I was in the United States and I was speaking at the chapel services and giving a lecture at a seminary, well known among Bible believers for upholding the truth, and which believes the right things and trains accordingly. But I was particularly asked to speak by the dean about evangelistic preaching, and I did so, and I contended for regular, specific, persuasive, evangelistic preaching. But to my astonishment I found that the young men in that seminary, mostly in their twenties, did not agree with me. When we had discussion afterwards, they were very unhappy about this. This was a commitment to something that was not a priority. They were telling me that this was not what they learned; it was not what they received in lectures. I have found that quite widespread in the days when I used to visit seminaries and speak quite a good deal years ago.
Some people recoil and say, ‘What, is that all we have, preaching?’ And you read it in the books these days, they actually do not think very much of preaching. Some Bible believers, they say, surely it would be more powerful and more effective if there was a magnificent performance, a play, or crashing music, to move the emotions. But no, the method of God is ‘by the word of truth, by the power of God.’ Through the power of God, that is greater than anything else we could possibly do.
