Clary shut her eyes. You didn't say no to an angel, no matter what it had in mind. Her heart pounding, she sat floating in the darkness behind her eyelids, resolutely trying not to think of Jace. But his face appear against the blank screen of her closed eyelids anyway - not smiling at her but looking sidelong, and she could see the scar at his temple, the uneven curl at the corner of his mouth, and the silver line on his throat where Simon had bitten him - all the marks and flaws and imperfections that made up the person she loved most in the world. Jace. A bright light lit her vision to scarlet, and she fell back against the sand, wondering if she was going to pass out - or maybe she was dying - but she didn't want to die, not now that she could see Jace's face so clearly in front of her. She could almost hear his voice, too, saying her name, the way he'd whispered it at Renwick's, over and over again. Clary. Clary. Clary.
"Clary," Jace said. "Open your eyes.
You can tempt me, desert me, or cause me great pain; you can create a dark world that my cause me to fear; you can rule your world with blood and terror, that's true.
But you can't win. And I know that. Weak as I am, with my imperfections and sins, even with all of my failing, I am stronger than you.
I will soon have a body. And I have my agency now. I will increase in my faith and knowledge and power. I am not perfect, but I will be, and there's not a thing you can do! I will become like the Father if I follow the Son. You are powerless to stop me. You can threaten and tempt and whisper lies in my ear, but you can't stop me, Satan; I see that so clearly now! I can stop myslef, yes, but only if I follow you.
And I reject you temptations. I reject your whispered lies. I reject you, Lucifer, and your entire plan. You have no power to control me. I am in control of myself. And try as you might, you won't control me on earth. We will defeat you in heaven, and we will deafeat you on earth. Here, or the earth, it doesn't matter; I am always stronger than you.
