I was thinking the other day, could the preaching work be another of the signs Jesus mentioned when he said many would come in his name and
perform many powerful works in his name.
23 “Then if anyone tells you, ‘Look, here is the Messiah,’ or ‘There he is,’ don’t believe it. 24 For false messiahs and false prophets will rise up and perform great signs and wonders so as to deceive, if possible, even God’s chosen ones. 25 See, I have warned you about this ahead of time.
The preaching work IS a powerful work, there is no doubt about that given the enormous number of languages the literature is published in and the billions of hours spent preaching.
The message they preach is not that preached in the 1st century.
Their message is misleading.
