When he was asked what made him think he could muster the strength to lift the car, JT simply responded: "Angels".
Stephen doesn't remember what happened because he passed out shortly after the car landed on top of him.
He is shocked his son was able to move the car by himself when it took the combined strength of his other 17-year-old son Mason and Stephen to jack it.
JT alerted his brother to call emergency services once the car was lifted off of their father. Mason is heard on the recording begging his father to breathe through the pain.
Stephen was airlifted to the hospital in critical condition but suffered no internal damage.
JT tried to lift the car later but was not able to. His mother Jodi Parker told East Idaho News: "This whole thing is a miracle. There's no other way to describe it."
"There's no way that little boy could have done that. I just felt that it was a responsibility we now have to tell people that miracles still exist."
JT was honoured as one of the Red Cross's East Idaho Real Heroes on Thursday.
