Josh Duggar, the eldest son of Jim Bob and Michelle of 19 Kids and Counting is giving his younger brother Josiah some sage relationship advice after the latter entered into a courtship with Marjorie Jackson.

For the Duggars, courtship means "purposeful dating" and Josh advised Josiah to decide where he and Marjorie will draw the line when it comes to their courtship, according to The Examiner. The tight-knit Christian family enforces a no-kissing rule and chaperoned dates during the courtship stage, and it really helps if the couple know their boundaries.

When he was courting Anna, who is now his wife, Josh recalled that they had to deal with a long distance relationship, but it also helped them maintain the boundaries they had agreed upon. "For Anna and I, we had 1000 miles between us, it made things a little easier," he said.

And since Josiah and Marjorie only live 10 miles from each other, they will have to get really creative when it comes to courtship. "I think each person has a different structure. I had all my good looks on my side. I'm not sure what you've got," Josh jokingly told his brother.

Earlier, Josiah said that his elder sister Jill handed him an extensive list of questions she and husband Derick Dillard came up with while they were dating, and he and Marjorie applied the same questions to their relationship.

"It was amazing. Every single question you could ever think of was in there," said Josiah.

Josiah and Marjorie have known each other for years, and they became friends first before entering into their courtship. 

"I met Marjorie a few years ago, when I was taking Spanish lessons at her house, and I was very impressed with the way she was with her siblings and her love for the Lord," Josiah told PEOPLE.

As for Marjorie, she felt an instant connection with the young Duggar boy. "For me it was an immediate thing. I have always admired him and his family," she shared.
