Don't you mean, 'truth, as of today, is always good to know'? With your "real teachers" your "truth" can be changed tomorrow and what you believe as "truth" today, will not be "truth" tomorrow. In your religion, you never know when your god will will new truth to be known that will change old truth.
Yes, just like He will ROTFL when a witness tells Him, 'you appointed a faithful and discrete slave that I was told consisted of 12, 8 and 7 men that CLAIM they were appointed by You and God, even tho You said, Matthew 24:23-24 (ESV Strong's) 3 Then if anyone says to you, ‘Look, here is the Christ!’ or ‘There he is!’ do not believe it. 24 For false Christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect., and the slave you appointed told me You came back in 1918 or 1919 and are HERE invisibly. I still believe these men because they told me they were the slave'!!!
