Wilson was raised in Charleston, Illinois, and attended Charleston High School, and joined the United States Navy upon graduation, where he served from 1977 to 1997.
He is an ordained minister in the Universal Light Church and a former president of the Horror Writer's Association. Wilson won the Bram Stoker Award for professional achievement in horror poetry.
His 1999 novel, This is My Blood (currently released as The Temptation of Blood), contains books of the fictional gospel of Judas Iscariot. This novel, which also features Mary Magdalene as a fallen angel cursed with a form of vampirism, oddly mirrors information recently translated in the coptic codex ascribed to Judas Iscariot. Both works feature Judas as being the best of the apostles -- the only one to fully understand Christ's teachings and lay down his own life for the salvation of all.
