Anakin guides Ben to the light script draft:

Ben senses a presence and turns to it. In the wide shot Anakin’s ghost appears.

Ben: “Grandfather.”

Anakin: “Ben.”

Ben: “Ben is dead.”

Anakin: “No. Kylo Ren is dead. Ben Solo lives. That’s why I’m here. (gentle pause) Ben, she will need your help.”

Ben: “It’s too late. She’s gone.”

Anakin: “It’s never too late Ben. You and Rey can bring balance to the Force. Finish what I started.”

Pregnant pause.

Ben: “I know what I have to do but I don’t know if I have the strength to do it.”

Anakin: “You do. We all do.”

Ben throws away Ren’s lightsaber, turns back and Anakin is gone.

As the camera pulls away for the wide shot, Anakin’s voice says:
“May the Force be with you.”
