1Pt1

Peter emphatically described life in Christ as being "born again" (v.25). His challenge was to live according to this new reality. He recognized that we lived in ignorance before knowing Christ, but challenges us to now live in obedience to Him. 

The word he uses to describe this new way of living was "holy". By this he means, set apart specifically for God. No longer living to please ourselves but living to pleas Him. Letting our minds and actions reflect a new reality to our lives. Caring more about the eternal dwelling that is coming than the present realities of the day.

Holiness is not being odd! Holiness is living in obedience to Christ. If we do today what God would desire, people would not think us "odd" but rather, exemplary. Make choices today that reflect the reality of belonging to Christ. That is holiness.
