Luke and Joel Smallbone, the brothers behind the Christian duo For King & Country, are hoping to inspire women to treat themselves with self-respect in their new movie "Priceless."

At the same time, Luke says they have to be very tough on guys because they are often the root cause of all women's struggles. Some might say that girls have to shape up first and the guys will follow, but Luke does not agree. "No! It's the other way around, the guys are the ones that have the perverted minds that are creating some of these issues that we have today," he says.

The Smallbone brothers say they came up with the idea for the "Priceless" movie when their older sister, Rebecca St. James, asked them to speak at mother and daughter conferences to highlight the importance of chivalry.

"We started to say to these women, 'Culture says to act and dress like you're cheap. But we say that there's a God who says that you're priceless.' We started playing events that guys were at, too, and we started saying to guys, 'It's time for us to stand out and step up — in our relationships, in our families, in our workplaces, and be men of Integrity and respect and honor," Luke shares with The Christian Post.

The brothers received a lot of positive reviews, with people saying their messages impacted on their lives.

The brothers thus decided to take things one notch higher. "So as our platform increased we got to tell more people about it. And that is the heartbeat behind why we wrote a book, and why we're working on a movie and all these different things," Luke says.

They understand that women crave acceptance, while some have identity issues. Some women even try to find their identities in their partners. But Luke says only God can make a person feel whole.

"I know that even in a great marriage with my wife, I can't deliver everything that she's hoping for in Jesus," he says. "The same goes for every girl who's looking to be fulfilled by a man, that's something, that's a lie ... For us to know who we are in God, for one, we become such a powerful individual because it doesn't matter what other people think of us; it matters purely in our relationship and what we have in God and that gives me so much confidence."

The Smallbone brothers even want to help people who have wrongly dabbled in the human trafficking industry. A lot of former traffickers long to be forgiven but struggle with guilt and shame, but Luke says God accepts people even at their worst.

"A lot of times people feel like we have to be good to come to Jesus; we have to have everything in order, and we need to have a good life before we can feel like we need to come to Jesus. That to me obviously is a lie from the devil, but also that's what makes Jesus so amazing," he says.

No matter how grave people's mistakes might have been, Luke says people should trust that their God is greater than anything else in this world. Once they surrender themselves to God, anything is possible.

"Priceless" will be released on Oct. 14.
