Having a strong, almost religious belief that someone will save or fix things, like a hero coming to the rescue.

for example

His messianic speech made the crowd believe he could solve all their problems overnight.

Think of a fanatic who acts like a savior is about to arrive—someone who talks as if their cause is the only way to fix everything. Why do people sometimes act messianic? Because they’re so convinced their way is the only right one that they sound like they’re promising a miracle.
