This sentence was asked by Professor Deng Xiao. At that time, the scene was that the professor called the guardian of God to call a doe, who was also the patron saint of lily. Remember after Sirius died, the patron saint of Tonks became a big dog? A truth. And "seven years" and "always" mean that his patron saint has been a doe for 17 years after Lily's death, suggesting that he has always loved Lily deeply. This sentence is super classic, second only to "look at me". The professor really loves Lily.
