Chris Tomlin's Christmas baby is here!

The popular Christian singer-songwriter, 48, and wife Lauren welcomed their third daughter, Elle Grace Tomlin, on Monday, Dec. 14, in Nashville, they reveal exclusively to PEOPLE. Tomlin — who is also father to Ashlyn, 9, and Madison, 6 — previously opened up to PEOPLE about the unexpected pregnancy, calling the new addition the "surprise of all surprises."

"Isn't she lovely … Isn't she wonderful … Elle Grace Tomlin has arrived to our world and we couldn't be more grateful," Tomlin tells PEOPLE. "She is precious and beautiful. Babies are miracles. Lauren and I are counting our blessings and soaking up our little 'miracle of love.' Time seems to stand still at the moment."

Inspired by the pregnancy news, Tomlin made a new Christmas song, telling PEOPLE about "Miracle of Love" back in October.

"I started thinking about how I could write a lyric that talks about my baby being born at Christmas and then talks about 'the baby,' Jesus, being born at Christmas, and that each line would match and would have a double meaning," he explained at the time.

Tomlin sings in the first verse of the tune: "I got the news today / I heard that you were coming / It took my breath away / and the tears filled up my eyes / Surely you'd change some things / the way that I was living / I hit my knees to pray / so grateful for new life."

The singer told PEOPLE that the lyrics aren't far off from how he really learned the news. Last spring, Lauren took a home pregnancy test after feeling symptoms, but "there's no way," she thought, according to Tomlin.

"When she got the test result, she said she just started laughing," he said. "She's like, 'Oh my gosh, are you kidding me?' "

To break the news to her husband, she gift-wrapped the positive test and gave it to him later that night. "I opened the present, and I was like, 'What is this?' I couldn't compute it. It wasn't going through my head. And then I almost passed out," said Tomlin.

The singer said he quickly thought how much a baby would change things for them — taking on the responsibility of another child — but soon, just as his song's lyrics say, he said, "you come around to the realization of what an incredible thing, what a precious thing, what a gift from God this is."

"It's an incredible privilege to be a dad with these girls, and especially girls," he added. "I feel like there's a special thing that a dad has with girls, and so I'm really grateful."
