believer

One who trusts

A believer is someone who accepts something as true, especially religious faith: She's a devout believer, He's not a believer.

Without qualification, believer usually implies religious conviction.

But it extends to any committed adherent: a true believer in free markets, I'm a believer in getting enough sleep.

The phrase make a believer out of someone means to convince a skeptic through demonstration.
