You reading the bible and going to church makes you just as much of a Christian as it makes me a wizard for watching Harry potter and reading the books. Last time I checked you smoked, drank, and had sex two weeks ago therefore you should be more understanding and help others find God, not judge them for the things they do. in my opinion drinking and smoking doesn’t make you a devil worshiper. No, that’s not the way a Christian should live but that doesn’t make you any less of a Christian and doesn’t make God love you any less. At the end of the day YOU should worry about YOUR relationship with God. If you’re too busy worried about everyone else, then you might not be as great of a Christian as you put on to be.
