Josh and Anna Duggar will celebrate 10 years of marriage this September and the looming milestone is clearly giving Anna food for thought after all their ups and downs.

Anna reflected on her decade of marriage to Josh in an Instagram post on Friday in which she thanked God for His 'redeeming grace.'

The couple are parents to five children and were frequently seen on the TLC reality TV show '19 Kids and Counting' about Josh's parents Jim Bob and Michelle Duggar and their 19 children.

They have had their share of trials as Josh was caught up in a scandal in 2015 when it emerged that he had inappropriately touched young girls, including some of his sisters, and that he had a membership with the cheating website Ashley Madison.

In the wake of the controversy, Josh entered a faith-based rehab facility for six months in Illinois.

Despite the revelations, Anna remained by his side.  In a joint statement posted to the Duggar Family website in March 2017, the couple revealed their continued commitment to their marriage.

'For nearly the last two years, we have quietly worked to save our marriage, focus on our children, and rebuild our lives together as a family,' they said.

'Doing so is never easy after a breach of trust. We've learned that a life of faith and rebuilding a life together is simply done one day at a time.'

They have remained together since then and even welcomed their fifth child, Mason, in September 2017.

In her most recent Instagram post, Anna acknowledged the difficulties but kept a positive tone as she thanked God for his blessings.

'The past 10 years have been a wonderful adventure,' she said. 'So thankful for God's redeeming grace and His blessings to us along the way.'

In another Instagram post back in March to celebrate Josh's 30th birthday, the faithful wife said: 'Happy Birthday Josh! I'm so thankful for the 30 years of life God has given you - I love you!'
