What does truth is powerful and it prevails mean?

Are you missing the definition of, "prevails"? That's really the only thing I can think of that could be unclear about this aphorism. (you could look up aphorism, too). The statement is one of those simple sayings that we hope is true because we like truth, honesty, uprightness, reliability. This is very close to the saying: good prevails over evil. In the saying you offer, however, there is a Word that is missing, though we know exactly what it means. Truth is powerful and it prevails (wins over) ... WHAT. The WHAT can be any number of things: truth wins over lies. truth wins over evil. etc. If we want to get deep here, we ask, "What is truth?" absolute? relative? non existent? human construct? Is TRUTH the same as FACT? But I don't think that's what you're asking. So, do you think truth is powerful?
