Thats technically a form of blasphemy, I would try to remove it from your vocabulary even if it is a habit. Think of it as though you gave your phone number to someone and they called you every time they got annoyed with someone else, then immediately hung up. Of course, they wouldnt *mean* to offend you, but it would still annoy you. Much the same with using God's title and Christ's name as an expletive.
