I suspect many's first response will be 'no', but christians lie every second on here, on debate forums, in their lives, while preaching etc, and god never followed his own rules. Like thou shalt not kill, than he goes and commits mass genocide. So if god's not going to follow his rules why would they?
LOL, look at the responses from Christians already! There's like 5 lies already on here. Calling the bible the 'word of god' for one, or saying that the truth is enough to bring people to jesus. Man, they lie like other people breath!
I'm not exactly sure what you would be lying about. The truth should be enough to win someone over. Jesus, son of god, came and died for our sins and rose from the dead to give instruction and then rejoined his heavenly father. There's nothing more to say.
