Paul William Waller was born at 3:42 a.m. on March 16, 2013, at his parents' home in Chicago, Illinois. He weighed 9 pounds and 11 ounces, and was 22 inches long. His first name is in honor of the character in the Bible, who was an "incredible hero of faith". His middle name is in honor of David's middle name.
In December 2015, Paul and his family moved to Big Sandy, Texas, after his father's job at the Institute in Basic Life Principles transferred from Chicago, Illinois to Big Sandy, Texas. On May 7, 2016, they officially moved into their new house after months of living in a nearby apartment and doing renovations. In August 2020, Paul and his family moved to Fort Worth, Texas, so that his father could start a new job working as a Pastor at Fairpark Baptist Church in Fort Worth, Texas.
Along with his siblings, Paul is currently being homeschooled.
