"Claire and I are excited to share that we are in a courtship," the 17-year-old said, noting he began seeing her after the two first met. "God brought Claire in my life and I wasn’t really expecting it, but he brought her along right when I needed her."
While the duo met in Spring 2018, Spivey said their families have known each other for nearly two decades. "I’m really looking forward to the memories to come spent with him," she shared. "I'm excited to see what the Lord holds for us in the near future."
The 14th child in the Duggar family confidently stated that he just knows "that she was the one," adding, "Claire has a lot of good qualities and I can sit here and tell you all of them, but there are so many good things that I see in her. I’m so blessed to have her in my life."
Spivey, the oldest of six siblings, said she really admires how Duggar is "serious-minded," but also has the "ability to have fun and see the bright side of things no matter what." She added, "He always looks for the best in people and I want to be more like him every day."
Justin's father, Jim Bob Duggar, explained to PEOPLE the difference between courting and dating. He noted, "Courting is getting to know each other in a group setting, both families spending time together and the couple setting goals together to determine if they are meant to marry," while dating often means the pair will see each other alone "and that sometimes leads to a more physical relationship."
The young couple's blooming relationship will be featured on Counting On's season finale.
Counting On airs Tuesday at 9 p.m. ET on TLC.
