Faith in the Force is a technology that can be researched at the Jedi/Sith Temple in Tech Level 4. It costs 750 Food and 1000 Nova, and makes the player's units 50% harder to convert. It is available to all civilizations except the Confederacy, Galactic Empire, and Trade Federation.
This is an important technology if the enemy converts a lot of the player's units, as the player will have far more time to kill the converting Jedi or Sith before they're finished. Republic forces should combine it with Jedi/Sith Purge.
"This important Tech Level 4 technology gives almost all your units the ability to more effectively resist Jedi or Sith conversion, making them half as likely to turn against you."
