“You are determined to hate him [Snape], Harry,” said Lupin with a faint smile. “And I understand; with James as your father, with Sirius as your godfather, you have inherited an old prejudice. By all means tell Dumbledore what you have told Arthur and me, but do not expect him to share your view of the matter; do not even expect him to be surprised by what you tell him. It might have been on Dumbledore’s orders that Severus questioned Draco.”
“And what will you give me in return, Severus?’ ‘In – in return?’ Snape gaped at Dumbledore, and Harry expected him to protest, but after a long moment he said, ‘Anything...”
“Severus Snape wasn't yours," said Harry. "Snape was Dumbledores, Dumbledores from the moment you started hunting down my mother...”
“When you do find your enemy, remember he will expect and welcome your hate. So surprise him, and let him fear your love.”
“If you merely pretend that you enjoy God or love Him, He knows. You can't fool Him; don't even try. Instead, tell Him how you feel. Tell Him that He isn't the most important thing in this life to you, and that you're sorry for that. Tell Him that you've been lukewarm, that you've chosen ___________ over Him time and time again. Tell Him that you want Him to change you, that you long to genuinely enjoy Him. Tell Him how you want to experience true satisfaction and pleasure and joy in your relationship with Him. Tell Him you want to love Him more than anything on this earth. Tell Him you want to treasure the kingdom of heaven so much that you'd willingly sell everything in order to get it. Tell Him what you like about Him, what you appreciate, and what brings you joy. 'Jesus, I need to give myself up. I am not strong enough to love You and walk with You on my own. I can't do it, and I need You. I need You deeply and desperately. I believe You are worth it, that You are better than anything else I could have in this life or the next. I want You. And when I don't, I want to want You. Be all in me. Take all of me. Have Your way with me'.”
“It seems to me there are things we should have talked about. Like, what happens if you think you've found the love of your life, but you notice, whenever you go into the city together, that he walks ahead of you in the subway station, and doesn't look behind for you until after he's gotten on the subway? And what if you find yourself wishing you did not have to tell him to wait for you? What if being with him starts to mean having to say those things..."Honey, what for me?" And you start to resent him making you do that in order to keep him walking by your side?”
