The Heidelberg Diary: Daily Devotions on the Heidelberg Catechism

My family used this for our family worship, it has been a great blessing. Our girls are quite young, so the page of material has never been a challenge for them to sit through, even when we doubled up after missing a day. The book does a great job of unpacking the beautiful and somewhat dense Heidelberg Catechism. The author I think is largely unobjectionable in what he presents, there were some minor disagreements, but not enough that it wasn't always enjoyable to read to my family.
