"If they were really just about women's health care, they wouldn't be doing everything they can to promote abortion," she charged.
Johnson also observed that abortion providers and supporters are not all irreligious.
President Obama closed his remarks to Planned Parenthood with a prayer: "God bless you!" Johnson said this should be a reminder that the organization's employees "believe they are doing God's work."
"People who work at Planned Parenthood or in the abortion industry believe that they are doing sacred work. Planned Parenthood has a large board of clergy, current or former ministers, that are supporting employees," she said.
"As someone who worked in the abortion industry, I get it. I used to think I was doing God's work too. I completely believed that I was a Christian and following God's will," Johnson continued. "I understand how people can be deceived in this way. Even our president. Even clergy. That's just the way that sin works."
She now wants to help Planned Parenthood employees realize they can leave the abortion industry.
"There is a place for them to go. They don't have to feel like they're trapped," she said.
"I believe, first of all, through my own personal experience, that there is something better out there for them. They were born to do something much bigger and much better than working in the abortion industry."
Recent abortion clinic scandals including deaths and malpractice at abortion facilities, financial fraud and the current murder trial of Philadelphia abortionist Kermit Gosnell are other good reasons for abortion workers to quit, Johnson explained.
"I want them to know that they can be held responsible for that," she said. "There's no time like the present to get out of the abortion industry and start living a better life."
