John mentioned Major Ian Thomas' teaching on "Sent, went, put" in his last sermon. We've included the short audio here. Below is an excerpt from his bio listed on the Torchbearers International website, the organization that the Major began in northern England at Capernwray Hall in 1947. You read read his entire bio here.
The Major was every inch a soldier. With his infantry battalion he served in the British Expeditionary Forces in Belgium at the outset of World War II and took part in the evacuation at Dunkirk. Often in combat, in France, Italy, Greece, and elsewhere during the long war, he found the Lord Jesus to be his complete sufficiency. The Major was likewise a soldier of Christ, faithful to the Captain of our salvation. He found life an adventure with God.
