Born in Belfast North Ireland, David Kirk was saved at the age of nine. He was active for the Lord as a youth being involved in village outreach where he and a group of youngsters used to visit the rural areas on bicycle to preach the gospel. He moved to Nova Scotia, Canada in 1931, marrying Molly Macartney, also from Ireland in 1932. On a visit to Ireland in 1947, 60 souls responded for salvation under his preaching. During this time he spoke every day of the week except Saturdays. Back in Canada, he settled in Hamilton and was involved with the Brethren Chapel until the time of his death. Throughout his life he was seen as a preacher with a burden for the salvation of souls, as well as a Biblical expounder.
