"Whatever for?"
"The Pattern's down there. It must be pretty colorful."
"Oh, it is?all bright and swirly. Rather intimidating, though."
"How can you say that when you've walked it?"
"Walking it and liking it are two different things."
"I'd just thought that if it were in you to walk it, you'd feel some affinity, some deep resonant kinship with it."

"Oh, while I was walking it I knew it was int me to do it," I said. "I didn't feel it beforehand, though. I was just scared then. And I never like it."
"Strange."
"Not really. It's like the sea or the night sky. It's big and it's powerful and it's beautiful and it's there. It's a natural force and you make of it what you will."

park sang joonI'd like to know if this structure is confined to the construction "It is in someone to do something."Yes, I think the subject may always be dummy "it". At least, I cannot think of any other cases.
There are also some related patterns, e.g. "to find/have it in one(self) to do something".
