Stephen J Drain

Saved, by the call and grace of God in Christ, in the mid 1980s. Today he would label himself an Evangelical Christian with strong Reformed beliefs, a “5 Point Calvinist.” Steve greatly involves himself in discussing the two “taboo” subjects: Politics and Religion. He tries to read and listen to a minimum of forty books a year and realizes that no matter what topic or genre, whether Bible, theology, Christianity, history, biography, philosophy, political, social commentary, pop-culture, or even fiction, they all tie together in a spider’s web of worldviews. His favorite author is C.S. Lewis, bar none. Other favorites include James R. White, J. Budziszewski, G.K. Chesterton, Peter Kreeft, and Os Guinness. He loves Charles Haddon Spurgeon. Steve’s hobbies are generally reading and writing, music, hiking, and laughing. He has been writing songs/lyrics since the age of about eight and has played in Christian bands. He has written poetry, several biblical studies over the past decades, and has even finished his first book manuscript entitled, “Shaken Faith: When God Has Let You Down” with co-author Al Rossi. He has also written for the now defunct Examiner website as the Philadelphia Christian Perspectives Examiner. (He wishes he could write some fiction.)
