And for good reason, my friend. The Bible has this to say about liars...
8 But as for the cowards and those without faith and those who are disgusting in their filth and murderers and fornicators and those practicing spiritism and idolaters and all the liars, their portion will be in the lake that burns with fire and sulphur. This means the second death.”
But, as I'm sure you know, the Watchtower Society has made clear that sometimes it's okay to lie. (Think Theocratic War Strategy.) Here we have a less cut and dried issue. The Society (while not blatantly condemning the Biblical stand) makes an "adjustment" to the clear Biblical teaching on lying. If the Society or its representatives urge you to lie about something, would you do so? Or would your own conscience possibly moderate it?
