I: I don't see you expose liars, I only see you exposing magic tricks!
A: Please understand the definition of "Lie" here:
It doesn't matter the purpose of the lie, whether is to achieve stealing or entertainment, still lies. One is less harmful than the other but still lies.
If the layman doesn't want to know the secret, it is respected; but when they ask for it, it is no longer respected by most magicians, at least there is a "quid pro quo", less and less people do favors or a humble gesture without anything in exchange.
(James 3:13-18): Who is wise and understanding among you? Let him show by good conduct that his works are done in the meekness of wisdom. But if you have bitter envy and self-seeking in your hearts, do not boast and lie against the truth. This wisdom does not descend from above, but is earthly, sensual, demonic. For where envy and self-seeking exist, confusion and every evil thing are there. But the wisdom that is from above is first pure, then peaceable, gentle, willing to yield, full of mercy and good fruits, without partiality and without hypocrisy. Now the fruit of righteousness is sown in peace by those who make peace.
(Matthew 5:14-16): You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works and glorify your Father in heaven.
