“If the bugle gives an indistinct sound, who will get ready for battle?”
In the passage quoted above, the apostle Paul is speaking of the use of the first century gift of tongues in church without the presence of an interpreter, but the principle has a more general application: indistinct sounds don’t get people moving. If you don’t know what you just heard, you can’t possibly act on it.
More importantly, the Lord cannot expect you to act on it, and he doesn’t.
