How about verses like:
Matt. 10:33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.Water Dogs and the like have an absolute heyday with that! Well, when dealing with someone who doesn't know how to Rightly Divide, that is. Me, I just tell him that Jesus was talking to a different group of people in a different age under different rules, and tell the guy to get lost (or saved, rather!). Others would just stammer and stutter and turn to a bunch of different verses to try to explain that away, when the fact is that they can't! If you believe that the entire Bible applies to you, right now, then you're going to have a real hard time explaining things like this.
Ok, I have to go to a meeting at church, so I can't continue. I'll work on this subject a little more after church. God bless.
