Back in the glory days of the American car industry Packard was the last company to get into advertising. It didn’t happen until the founder died because whenever he was asked to buy advertising for his cars, he would always say: ‘I don’t need to advertise Packards; just ask the man who owns one.’ And after his death, ‘Ask the man who owns one’ became the Packard slogan; and it worked.
In the same way, faith in Jesus has also been spread primarily by word-of-mouth. The Shepherds at the first Christmas may have heard the good news from angels, and the Wise Men were led by a star, but most people who come to faith do so because of the influence of someone whose life has been changed by it.
What’s the value of faith? Just ask the person who has it.
