Remember that sometimes we think we are hearing God’s voice, but it may not be Him at all. Full Article
Not only do they go to church, but Abby (Johnson) truly believed she was doing what God wanted her to be doing when she was with Planned Parenthood. Dr. Tiller was killed while attending church. Abby can tell many stories about women who wanted to pray while on the table about to get an abortion. 
Sometimes, she would recognize women that would come in to Planned Parenthood, because they attended the large Baptist church where we taught Sunday School. Some of the people she worked with attended church regularly. Remember that sometimes we think we are hearing God’s voice, but it may not be Him at all. There have been people who are anti-abortion who say that “God told them to kill an abortion doctor.” Or maybe that “God told them to blow up an abortion clinic.” But if we know the person of God, we know that He would never instruct us to harm others. I suspect that when Abby thought God was blessing her work and telling her to keep doing what she was doing, it wasn’t God’s voice she was hearing.
