So, vpw did teach others. So, if the first part of the alleged 1942 Promise was correct, then it was completed, like a contract, with both parties delivering what they were supposed to. But, did vpw teach "God's Word like it hadn't been known since the 1st century"?
No.
First, nearly 100% of everything he taught has been traced to other Christian writers or teachers whom he plagiarized. So, each of his teachings was on something as someone knew in the 20th century already. Was that a made-up promise, or was it the promise of a being so uninformed it didn't know people were already teaching the Bible and writing about it? Or was it a lying spirit that promised this? The possibilities vpw was listening to a lying spirit or a stupid god are even worse than vpw just lying and plagiarizing.
Second, what was "God's Word as it was known in the 1st century"? Nothing like twi! People knew God's Word by experience and in power. The written texts studied ad nauseum in twi were largely UNKNOWN in the 1st century. People read the Torah, taught, prayed, healed, and saw miracles. The selling points of Christianity were results, not clever men at pulpits teaching a new Greek word or making a bad joke. Christians were decentralized, Christians had no head honcho on the Earth, Christians had no codified "Statements of Belief." Christians weren't tithing. Christians weren't buying books or paying money for classes. In short, the 1st century Christians did NOT resemble vpw's claims or twi in any way other than vpw CLAIMING they were the same. Talk is cheap, and the reality was VERY different. If you want to see something of the 1st century in vpw's work, review the "ministry" of Simon the sorcerer.
