Aside from the one special ring comprised of numerous gemstones, the Duggars also celebrated their wedding anniversary by sharing love letters for each other on the family’s official blog.

In Michelle’s note to her husband, she stated how she feels about his best qualities, including fear of God and humility.

“Recently, when one of our daughters asked, ‘Mom, what one quality should I look for in a future spouse?’, as I considered the answer, I realized what it is that I admire so much in you, Jim Bob,” Michelle wrote. “It is that you LOVE & HONOR God and in humility you are open & transparent with me, simply put, HUMILITY and the FEAR OF THE LORD.”

The TV personality also added that she remains grateful for her husband to share his love, hopes, dreams, strengths, weaknesses, victories and failures with his wife.

In the same way, Jim Bob wrote a note for Michelle, stating that she is the “greatest blessing” of his life and truly exemplifies a “Proverbs 31 wife.”

“She is my best friend, we share everything. Michelle is selfless, always thinking of others first,” Jim Bob shared. “She is an example to millions of women, her children rise up and call her blessed. Michelle is my business partner, ministry team companion and the mother of our 19 children.”
