A deeper look at the Old Testament yields a very important piece of information - the purity terminology used both in the ritual and in the spiritual contexts are the very same. This powerfully indicates that the ritual prescriptions of the Old Testament also have spiritual meanings. What ethical message does this have for Christians? That question is really the subject of this book which can be used for both personal and group Bible Study. Contents Preface Chapter 1. Integrity, The Heart of the Kingdom Bible study 1.

He grew up in the Netherlands and started studying forestry with an intention of returning to tropical mission fields to serve in forestry related to mission. It was during this time that he felt the calling to study theology. He enrolled in the Theological University in Kampen, Netherlands and completed his Masters in Old Testament Studies. He then embarked on a pastoral career that spanned over 40 years in the Reformed Churches in Netherlands. During this time, he pursued a PhD in Old Testament Studies and submitted his thesis on Purity Terminology in the Old Testament. Since his retirement as a Pastor, he has served as the moderator for the General Synod of the Reformed Churches in the Netherlands for two terms. He has been happily married for 46 years to his wife Hannie, and God has blessed them with 7 children and 18 grandchildren.
