Is there a holy ghost in the story of an Idaho couple who decided against aborting their babies?

I've been wondering about that since I first read a front-page Houston Chronicle story earlier this month about the Torres family's experience:

Dad held the babies upright on his chest, patting them and swaying, while Mom crammed the last bag between a cooler of donated breast milk and a new portable crib.

“Well,” Chelsea Torres said, closing the trunk and turning to her husband, Nick, “it all fits.”

That was the easy part.

What lay ahead was far more daunting.

Leaving the hospital with a newborn is a moment no parent is ready for. What if the baby screams in the car? What if she won’t take a bottle once you get home? Chelsea, 24, and Nick, 23, have an even darker worry: What if the girls don’t survive the drive?

The doctors assured them everything should be fine, but it’s hard to shake that fear. They’ve carried it for months, ever since the doctor back in Idaho told them Chelsea was pregnant with conjoined twins. Ever since they decided to ignore his recommendation to have an abortion. Ever since they loaded their 3-year-old son, Jaysin, into their Kia Optima six months ago and drove 25 hours to Houston.

“I’ve been dreading the return,” said Nick, dark circles under his eyes after days with little sleep. “I’m just glad we’re making it with two healthy babies.”

My question is simple: Why? 

Why did the couple choose not to have an abortion? Were religious beliefs a factor? The Chronicle story that I read did not explain their thinking, so I Googled in hopes of finding more background.

I came across a more in-depth Houston Press story as well an Idaho State Journal feature from months ago, but neither fully answered my question.
