Even though Derick and Jill Dillard's wedding and honeymoon are over, love continues to be in the air throughout the Duggar household from hit reality TV series "19 Kids and Counting."

Jessa Duggar and boyfriend Ben Seewald appear to be headed toward marriage as well, after courting for several months and recently going on an extended trip to Central American together.

Many speculated that they had gotten engaged while out of the country-but  Duggar patriarch Jim Bob was quick to explain that it was a missionary trip and the couple wasn't alone. Traveling alongside the couple were Duggar chaperones as well as other missionaries.

The "19 Kids and Counting" stars reportedly spends a great deal of time doing missionary work, as the two are known to be active members of their church. Their strong faith brought them together in September  of last year, and the two have since taken their courtship quite seriously.

During their mission trip, Ben and Jessa shared several Instagram photos with fans. The latest photo shows the couple smiling together with the caption, "Shared a wonderful two weeks in Central America with my BFF! Such a special time of serving Jesus together!"

Jim Bob and wife Michelle are also celebrating a special time. The couple's 30th anniversary falls this year, which they will celebrate by going to a special lunch and then spending time with their family.

"[I'm] looking forward to 30 more happy years together," Jim Bob told ABC News

Their daughter Jill congratulated her parents on the milestone, posting a picture of them on Instagram with the caption, " Happy 30th Anniversary to the best parents ever! We love you! Derick and I share the joy as we celebrate our first 30 days together and look forward to our next 30+ years together!"

30 years ago, Jim Bob and Michelle's wedding was "sweet and simple." Because the family didn't have much money, Michelle recalled that she and family members did all of the wedding decorations and food  themselves. Michelle wore her mother-in-law's wedding dress, made her own wedding cake, and decorated with crepe paper and silk flowers. However, Jim Bob and Michelle made sure to spend money on their honeymoon, as it was "the first time to be alone together."
