Why does Paul use the trumpet as an illustration of battle commands?
Paul uses the trumpet because it was a familiar signal for battle commands; an uncertain trumpet blast leaves soldiers unsure and unprepared. The illustration reinforces that sounds, including ministry, must give a clear distinction so hearers know what is being communicated.
Les explains that Paul is using simple, everyday illustrations. In verse 7, instruments without life—whether pipe or harp—must give a distinction in the sound; otherwise it is just noise, and no one knows what is piped or harped. In verse 8, Paul applies this to the trumpet: if it gives an uncertain sound, who shall prepare himself to battle? Les notes that the Romans used the trumpet for battle commands, much like American cavalry riders did with their trumpets in the movies. So the trumpet illustrates the need for a clear, distinct sound so people know what is being signaled.
For if the trumpet give an uncertain sound, who shall prepare himself to the battle?
