Books by Puritans are often regarded as inaccessible because of the depth of their theological thought, but these men also had a pastoral and evangelistic heart. This is very apparent in The Good Work Begun, where Thomas Vincent speaks directly to teenagers in his congregation regarding the state of their souls. Based on Philippians 1:6, he draws out the nature of the work of grace in a soul, and then shows that this work, once begun by the Lord, makes an eternal difference to the soul. “Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ.” (Philippians 1:6)
