Dr David L Cook ( 1932 - 2013) was a highly experienced Scottish educationalist and Bible teacher. He worked in education all his life, first as a classics teacher, and then secondary school headmaster. He studied the Bible continually throughout his life, and was familiar with NT Greek and also Hebrew. As well as his MA in the classics, he obtained both a BD and a PhD in Theology. From a young man until his late 70s, he travelled all over Scotland, and beyond, preaching and teaching, mainly in Brethren churches. He wrote several Bible Study booklets, which he had hoped to revise and make available, but he passed away before that work was completed. His family have completed that work and the studies are now available as the Epistole Bible Study Series. ┬а ┬а
