Often, we take our salvation for granted and we begin to take in consideration things that compromise our relationship with the Lord. Our strength is in our relationship and our salvation is in our obedience to his word. Do not believe that your lifestyle does not matter, and your relationship is so secure that you allow sinful things to enter in and separate you from the protections of God which came from your sanctified lifestyle.  It is a fearful and dreadful thing for the God of all creation to depart out of your life and leave you as you were before your awakening and conversion.
