A cousin of mine will be getting married in the near future. She and her husband-to-be are professing Christians. They attend a broadly evangelical church. However, I am not sure that either of them know very much and am not sure how sound their professions truly are. For their wedding I want to get them a book that will be useful to them as they start their new family. I am looking for something that will clearly hold forth the gospel as well as maybe offer insights on things such as as family worship or other such things for a couple that has probably never heard of the concept. I am open to Puritan suggestions but keep in mind that neither of them has probably ever read a Puritan before!
