When people hear competing--even contradicting--descriptions of holiness they sometimes become doubtful it can be a reality in their own lives. Like most divine things, holiness is difficult to describe and capture in one complete way. This work embraces the richness of holiness by putting side-by-side various understandings of holiness and sanctification from a diverse group of Nazarene pastors, leaders, and scholars. These writers demonstrate the variety of ways this work of God is understood and lived out. The contributors are aged twenty-something to eighty-something and are a mixture of amateurs and experts in the field of theology.Holiness is a dynamic reality that exists in tensions such as instant and process, now and later, and individual and social. One thing is certain, however: holiness is a gift from and a work of God that He originates, initiates, and sustains in the life of the believer.
