Amanda Berry, Gina DeJesus, and Michelle Knight were rescued Monday after a neighbor heard Berry screaming for help. Also rescued was Berry's six-year-old daughter. Berry, her daughter, and DeJesus are safe with their families, while Knight remains at a Cleveland hospital.

The women's captor, 52-year-old Ariel Castro, was recently charged with four counts of kidnapping and three counts of rape. He could face more charges once the case goes to a grand jury.

In charging documents released Wednesday, police said Castro lured Knight into his car in 2002, took her to his home, and "repeatedly sexually assaulted" her. Authorities described a similar scenario for Berry, who was lured into Castro's car in 2003 on the same road as Knight.

The following year, DeJesus was lured into Castro's vehicle and, like the other two women, repeatedly sexually assaulted in the subsequent years.

This story shows how most human trafficking cases start. You see, trafficking doesn't require movement; slavery is at the heart of this global problem.

According to the U.S. Department of State's 2012 Trafficking In Persons (TIP) report, "People may be considered trafficking victims regardless of whether they were born into a state of servitude [or] were transported into the exploitative situation…. At the heart of this phenomenon is the traffickers' goal of exploiting and enslaving their victims."

Cathey Anderson of Operation Mobilization says their annual Freedom Climb helps fight the problem worldwide.

"We're just all out there being this voice for these gals," Andersons states.

Each year, women climb one of the world's toughest mountains to raise awareness of the issue. The first Freedom Climb tackled Mount Kilimanjaro, while this year's group took on the foothills of Mount Everest.

"We walked into it with the anticipation that it would be very similar to our Kilimanjaro hike," Anderson recalls. "But it turned out to be dramatically different in so many different ways."

Along with a longer hike and more difficult terrain, sickness took down a majority of the group.

"Think of the worst stomach flu you've ever had, and that explains it," says Anderson.

"It was a struggle! It was just an absolute push-through, give it everything you got, and just depend on the Lord."

The climb does more than raise awareness though; Freedom Climbers also raise support for OM projects that fight human trafficking. Anderson says their projects tackle the issue in three ways: prevention, development, and rescue. Learn more about them here.

One of the best aspects about this story? You can be a part of it.

"We really need to get out there and be aware, be the voice, be the hands and the feet, and start making a difference," says Anderson.

Keep praying for the victims of modern-day slavery, and pray for justice for the women in Cleveland.

"Pray for those that are suffering–physically, mentally, emotionally–and oppressed, enslaved, whatever it is, because it doesn't end," says Anderson.

"It's a big, bad stain on all of humanity."

"So many of us have this mindset that human trafficking and slavery is a third-world issue, and it's not," says Cathey Anderson of Operation Mobilization. "It's here in our backyard."

Three women and a 6-year-old girl were rescued from a literal "house of horrors" on Tuesday. Neighbors broke in and called the police after they heard one of the women screaming.

Amanda Berry, Gina DeJesus, and Michelle Knight went missing between nine and eleven years ago. In 2002, Knight was thought to have run away. Berry vanished in 2003 after calling her sister to say she was getting a ride home from her job at Burger King.

The following year, DeJesus disappeared while on her way home from school.

The girls' families hoped for the best and held annual prayer vigils in their honor. But the fate of Berry, DeJesus, and Knight was one worse than death: they were all kept as slaves in a run-down Cleveland home.

"We can't close our eyes any longer," says Anderson. "This is a reality that we are living in."

If denial is no longer an option, how should Christ-followers respond?

First, "We need to acknowledge that spiritual warfare is very real, and it's a battle we all need to engage in," Anderson says. "Number two, we need to educate ourselves. We need to be aware of what's going on in our community."

Those who claim to follow Christ also need to examine their personal lives and habits, she adds. According to the Women's Rights and Services division of Brigham Young University, 47% of Christians say pornography is a major problem in the home.

It's not just a problem for the men, however. One of 3 visitors to all adult websites is a woman, and over 9 million women access adult Web sites each month.

"We have a personal responsibility to clean up our own house before we can even begin to address the needs of the community and society as a whole," says Anderson.

In addition, studies found that extensive viewing of the type of pornographic material commonly sold at adult bookstores was linked to a higher willingness to commit rape or other forced sexual acts.

Pray for purity as you engage in this battle.

Praise God for the miraculous rescue of these women. Pray for those in oppression who still need to be saved.
