There was an emphasis on Jesus being the only one who came from heaven and therefore this was the only reliable source about heaven and this is very important and gives a kind of clarity that is hard to ignore.
As it goes in John 3:13, no man has ascended to heaven. It was easy to pause and think on assumptions about figures like Elijah. What this stands at most is the discipline that is being encouraged the discipline is to let scripture interpret scripture and this is simply this is simply a separate tradition of stories.
Brother Eli is giving a strong message between what people say and what the Bible actually says. This teaching is about diving deeper to showing that the one who ascended is the same one who descended.
Whether you agree with every conclusion or not, this approach also allows us to think critically, to go back to that verse and to weigh everything against the word of Christ himself. And honestly, this kind of clarity that is very fresh and in the world full of so many noise.
