A Christian conference challenging men to become mighty men of God drew at least 250,000 men and boys to Greytown, South Africa, last weekend.

Hosted by farmer turned evangelist Angus Buchan, the Mighty Men Conference was the largest gathering at his farm, known as Shalom Ministries, since he launched the event seven years ago. Some estimate the attendance was as high as 300,000 during the meetings, which began Friday and ended Sunday.

“I have farmed maize. I’ve seen a lot of mielies [corn], but I’ve never seen a crop of people as big as this,” said Buchan, whose autobiography, Faith Like Potatoes, was popularized in a 2006 film that released in the U.S. last year.

Through three days of evangelistic meetings often marked by signs and wonders, Buchan challenged men to become godly leaders in their homes and to rid themselves of such sins as adultery, fornication and hatred.

The event was centered on the theme “watchmen of the house,” drawn from Ezekiel 3:17, which says, “Son of man, I have made you a watchman for the house of Israel; therefore hear a word from My mouth, and give them warning from Me.”
