Not true, in revelations we read about hell. Only the universalist unitarian cult believes in what this pastor is teaching.
The OT doesn’t mention much about hell because the ancient Israelites, like most people at that time, gave little thought to life after death. This was true of the Europeans, Semites, and Asians. All were mainly only concerned with this world, and only the Egyptians really had a strong belief in the afterlife.

To be fair, in Revelation (no “s” at the end) we read about a LOT of stuff that is mindbogglingly controversial. Pre-tribulationists see the rapture in chapter 4, while mid-tribulationists see it in chapter 7. And the other chapters spawn no end to controversy.
If revelation is your only source, you are not going to get very far convincing people of your theory.
