How exactly would you define Holy? It is my belief that to be Holy is to be like God. Sin is when we don't act like God or with the goodness and love of him. Through Christ God's image is fully restored in us, and through the spirit we are to walk and live in a way that God would walk. People who do not have Christ do not walk in the way they were created to walk. The mirror is broken so to speak. But how do you define Holiness? What is considered Holy, what is not?
