Austin Forsyth is counting the many blessings in his life.
In a sweet Instagram post on Thursday, the Counting On star shared a throwback photo of his wife, Joy-Anna (Duggar) Forsyth, smiling and holding a bouquet of gorgeous orange flowers that he sent her a year ago.
“One year and a day ago I sent Joy these flowers while I was at flight school,” Austin, 23, captioned the image.
“It’s amazing how life can change in just one year,” he added. “I am so blessed to have a wife that loves Jesus and me. #Godisgood.”
Much has changed for the duo throughout the past 12 months.
The pair were friends for 15 years — Joy-Anna, 19, first met Austin when his family moved to Arkansas and started attending the Duggars’ church — before they entered into a courtship last fall, which they announced on a special episode of Counting On: Jinger’s Wedding in November 2016.
