Well, I don't always feel fire myself . In terms of keeping the fire, I go back to Scripture again, where you didn't have a situation with a bunch of perfect saints. They had a host of problems. Paul talks about the Corinthians. I think there was incest goin' on there, immorality, drunkenness, debauchery.
Nothing really changes.
God never promised that. What He promised was infallibility and indefectibility of doctrine. So even popes are not perfect saints. We do have saints, too, but it's a different question from the nature of the true Church. It's always been the same.
