Duggar sisters insist they've forgiven Josh as they return to reality television in new TLC series

The upcoming season of TLC's new reality show will show Anna Duggar visiting her disgraced husband as he undergoes continuing rehabilitation for what he describes as an addiction to pornography.

The prodigious evangelical Christian family will return March 15 to the cable TV network with the first full season of "Jill and Jessa: Counting On," focusing on the two eldest married daughters, reported People.

The new season continues a three-part special that aired in December, and will show Jill Dillard and her husband continuing their missionary work with their young son in Central America and Jessa Seewald and her husband adjusting to life as new parents.

The sisters admitted during a Fox News interview that their eldest brother had molested them about a decade earlier, as children.

TLC suspended the family's long-running series after the molestation and apparent cover-up attempts by parents Jim Bob and Michelle Duggar were revealed, and the network eventually canceled "19 Kids and Counting" after Josh Duggar admitted to multiple infidelities.

"I definitely have forgiven Josh," Jessa Seewald told People as she promoted her new series. "It is a process, though, that you have to work through in your heart, and trust is not quickly rebuilt. It is something that takes a while. We love him very much, though, and we are very hopeful for the future."

Another sister admitted she was also struggling with accepting her brother in the wake of the scandals.

"I have forgiven him and I feel that, but the trust is not there," said Joy Duggar.

A video promotion for the new series shows Anna Duggar as she visits her husband at a religious rehab facility in Illinois.

"I don't know what I'm stepping into," said Anna Duggar, who gave birth to the couple's fourth child in July. "I don't know how to handle each situation. It's not anything I ever would have thought I would walk through. [I tell myself,] 'Just do the next right thing, have the next right response for the next 15 minutes.'"
