David Clarke was born in Oldham, Lancashire, in 1949. He was educated and trained as a lecturer, at Wolverhampton Polytechnic, and graduated with a Certificate in Education, awarded by Birmingham University, in 1978. However his earlier life had been rather different. He and his brother Michael were both convicted criminals and were sent to prison for malicious wounding and carrying a fire arm without a license. They grew up in Aylesbury, Buckinghamshire, during the 60's, and they were MOD's where they became criminals. On the 16th January 1970, David had a bad trip on LSD, during which time he called out to God to help him and Jesus spoke to him. He learned to read to educate himself and went on to Higher Education and for the next 14 years read the bible, various classical christian literature and joined the Bierton Strict and Particular Baptists, in 1976. He became a lecturer in electronics, the church secretary and was called by the Lord, and sent by the church to preach, in 1982. The Bierton church became a Gospel Standard listed cause on 16th January 1981, Michael, David's brother was unaffected by David's conversion and continued his flamboyant style. Due to errors in doctrine and practice David withdrew from the Bierton church and wrote his first book, "The Bierton Crisis"', that explains the reason for his secession and with a view to help others. In 1995, David got news of his brothers arrest and later imprisonment in the Philippines and his conversion from crime to Christ, in 1999, that was 5 years into his 16 year prison sentence he published their story in, "Converted on LSD Trip". David then went on a preaching mission to the Philippines in order to bring relief and help to Michael. During this mission David and Gordon Smith preached the gospel to hundreds of convicted criminals, including many on Death Row. This story is told Michael and David's joint book, "Trojan Warriors" that contains 66 life giving testimonies, of some of the most notorious criminals in Far East Asia, who had become Christians in New Bilibid Prison. David writes of his ongoing mission work in his other publications."And he was astonished, and all that were with him, at the draught of fishes which they had taken": Luke 5 verse 9.
