|Bunyan's autobiographical memoir, GRACE ABOUNDING TO THE CHIEF OF SINNERS,, written when he was 38 years old, is mostly a chronicle of his spiritual life; little is known about the practical details. Born to a humble family, son of a tinker, Bunyan was taught to read at a grammar school, but became a wandering tinker like his father. When he was 16, he was drafted into the army, where he served for three years, and soon after underwent a religious conversion, finding in Puritan ideas the remedy he sought for a restless conscience. In 1655 he became a preacher among the Bedford Baptists, who were known for pacifism and the strict interpretation of scripture. Married twice, Bunyan produced six children. After the restoration of the monarchy in 1660, it became against the law for anyone to preach unless he was ordained, and Bunyan was imprisoned in Bedford Gaol for 12 years. When he was released in 1677, he returned energetically to preaching in the more liberal political climate of the time. His great work, PILGRIM'S PROGRESS, was published in two installments in 1678 and 1684. Bunyan died after being out in the rain and catching a cold.
