How did James and Lily Potter defy Lord Voldemort?

Answer:
The prophecy says that the baby would be born to parents who have thrice defied Lord Voldemort. It isn't known how they defied him these three times.

Lily Potter defied him a fourth time by refusing to allow Voldemort to kill Harry Potter when he was a baby.
