A number of girls are expected to cancel their abortion appointments after talking to students during the day of protest, as has been the case in past years.
Kemper said one girl had already changed her mind against aborting her pregnancy even though this year's protest does not take place until Tuesday. According to Kemper, the girl had been listening to the music and reading the information presented on the ministry's MySpace website.
"I had tears in my eyes," Kemper said as he recalled the moment last week when he received the girl's message. "Every time we hear that, it reinforces that everything we do is worth it. There is someone who is going to live now."
While the pro-life leader has dedicated 15 full-time years toward protecting life, he takes no credit for the lives of the unborn that are saved as a result of his efforts.
"I believe that I have never saved a single baby's life," said Kemper. "I believe that God does that."
He added, "We've been so thankful that God has used us as a tool."
Although there have been victories for those taking part in the protest, there have also been many challenges.
Some students are yelled at or ostracised for standing up for their beliefs.
"We actually get more reports from students who get harassed by school teachers and staff than by students," said Kemper.
Other challenges stem from mobilising the youth to be "Christians on more than just Wednesday and Sunday nights", according to Kemper.
He said he hoped this generation would model after Queen Esther, who - as a very young woman - risked her life by entering the king's court in order to speak out for her generation.
And that is what Stand True Ministries strives for, said Kemper. The group's mission statement says the group "is committed to educate, equip and activate young people to stand up and be a voice for their generation".
It is estimated that 6.7 million abortions have been carried out in the UK since abortions were introduced 40 years ago.
