[Star Wars The Force Awakens] Why is it so important to find Luke Skywalker?

Why is everyone so intent on finding Luke Skywalker that they're willing to die or kill?  What advantage will Luke offer to the resistance beyond being one more skilled pilot/ground combatant?  The First Order expends significant resources and time attempting to track him, so they must think he can somehow interfere with their plans.  What can one Jedi Master do in the face of the First Order's military might?

A single force user can shift the tide of a battle, they are force multipliers whose presence alone can inspire soldiers to go above and beyond, while also demoralising the enemy.

They also make excellent commandos and covert operatives - you can't use your great big super weapon if some force happy zealot goes postal inside the command centre and/or destroys key components.

The First Order wanted a monopoly on force users to ensure their success. A Jedi Master can train other users, even a neophyte infiltrating a key facility is capable of evading capture long enough to do some serious damage, and poses a major threat to their plans for Magic Space Wizzard superiority in the theatres of battle.
