1. You CONFLATED lying with deceit... there is a big difference.
2. My tongue does not plot destruction, it plots CONSTRUCTION.
3. Deceit can have a difference in form and degree, adultery, etc, cannot...
To prove point, Jesus demonstrated that theft can sometimes be fine, for example, Jesus taught that it was fine to eat some food from another person's 'farm' if you needed it... so obviously, there is a difference in degree for some of the things which we are instructed to desist from doing... at its lowest degree, theft is fine and good, likewise, deceit, in its lowest degree, and in pursuit of righteousness, is fine and good.
4. Deceit does have truth though, again, you conflate deceit with the absence of truth, the practice of deceit and the uttering of truths are not mutually exclusive, again, lying and employing deceit is not the same.
5. The Kingdom of God can advance through several means... who are you to determine how and how not the Kingdom of God can advance?
Oh right, you are in no place to determine how and how not it advances, the Bible determines, but ultimately, God is the final arbitrator as to how His Kingdom is to advance.
You are yet to provide any scripture which demonstrates that my form of deception is inconsistent with Biblical teachings.
Yet, I have provided numerous examples and proofs and disproofs.
