That is convenient to say the least.
However it does lead to a couple of “issues”
First your leaders are not simply just preachers or ministers but full blown “prophets of god”. That is no small matter if you believe as Christians do that a Prophet is a very special individual. In fact it produces a contradiction with in the first words of your statement above, because a prophet speaks for god, who as you say, has the final word.
Second, another issue you introduce is the fact that if you recieve a revelation from god the runs counter to a revelation of a “prophet" of what I would assume is the same god, how exactly do you resolve that? I would think you would default to what god tells you vs. the prophet, but then you are in a quandary, for you are now part of a church that is lead by a false prophet.
So what now?
It is not convenient at all. It means I am entirely responsible for what I say and do, and I will answer to God for my conduct. I cannot blame any another man for my failures.
