Holiness is not a separate compartment of your life that you can switch on and off at will. It is in full effect 24 hours a day, seven days a week and it happens in the context of your relationships, not just in the secrecy of your prayer closet.
You don’t cut yourself off from the rest of the world in order to live a life of holiness. The monks and the ancient mystics got it wrong. When God called you to be holy, he meant that you live it out in the middle of the usual busy-ness, boredom, and drama of life, not just in the middle of the sugary sweet smiles of people in a church service.
