It seems as though Jessa Duggar and her sister Jill have a lot to say these days following their brother Josh Duggar's rather scandalous summer. Following his admission that he cheated on his wife Anna with an Ashley Madison account, Jessa is now giving her fans advice on how to avoid adultery while possibly taking a dig at her brother as well.

Jill, Jessa Duggar News 2015: Sisters Criticized For Their Sexual Awareness Campaign

According to Page Six on Tuesday, Jessa apparently knows what it takes to have a fulfilling marriage with a faithful partner by her side.

The reality television star said, "In three minutes, John Piper explains how God cures our heart's broken desires for sin," before adding, "When the Bible calls us to live like Christ, it doesn't merely give us a set of commands. It presents us with something compelling and captivating that changes our minds, and then our hearts. The gospel convinces us of something irresistibly true, and then transforms our desires for something new. That conviction and passion keeps us out of bed with someone who's not our spouse and rejects a thousand other temptations."

Jessa Duggar & Ben Seewald Called 'Hypocrites' For Wanting To Be On Television Again

Jessa is not the only person in her family taking a swipe at Josh, who is currently in rehab for his sex addictions. Her father-in-law Michael Seewald also took aim at the disgraced Duggar, slamming him for being a Christian "pretender."

He wrote in a blogpost, "While proudly saying things like, 'Our family is like the epitome of conservative values,' he was looking at porn and soliciting affairs. He took a job at the Family Research Council that exists to promote the traditional family, all the while undermining his own family by violating his marriage covenant. He flourished in the fame of his family and the success of their television show, all the while betraying their trust and Christian values. To the person reading this, I want to caution you. Josh was a pretender."
