Holiness is one of the more important realities in our understandingof who God is, of the life that God wants Christians to live and, indeed, of all the blessings of Christianity. We sing praises in church about the holiness of God. Christians desire to become holy as God is holy. This desire is encouraged in both the Old and New Testaments. God views us as holy through the redemptive work of Jesus Christ; and by the work of the Holy Spirit, God acts to make Christians increasingly holy-more godly, more like Christ. It is notenough for Christ to be our Savior; he also wants to be the Lord of our lives in all that we think, say, and do. This book may be used to study the biblical understanding of holiness in general; it also may be used as a devotional guide to holy living.It is as relevant to college, university, and seminary contexts as it is to adult Sunday school classes, weekday small group gatherings, or individuals interested in becoming more holy, more like Christ. It is not necessary to read through the book sequentially; each chapter is self-contained. Thus, readers may want to look at the Table of Contents and choose the chapters of most interest.
