Holiness is the key principle

‘1. The plan of Scripture for a Christian walk is twofold: first, that we be instructed in the law to love righteousness, because by nature we are not inclined to do so; second, that we be shown a simple rule that we may not waver in our race. 

‘Of the many excellent recommendations, is there any better than the key principle: Be thou holy, for I am holy?’

-John Calvin, Golden Booklet, chp 1 [and, Institutes, Book III, chp 6]
