In this piece, Elizabeth Prata of The End Time answers these questions. Romantic eroticism is the term she uses to describe the way in which some professing Christian women describe an encounter they supposedly had with God. Beth Moore claims she had an experience with God where she felt as if He was enfolding her; likewise, Sarah Young had a feeling of being enveloped by a warm mist and becoming aware of a lovely Presence. In her writing, Ann Voskamp promotes pagan nature religion or mysticism. So it should come as no surprise that she expresses romantic feelings about Jesus and is looking for satisfaction.
Now listen as Elizabeth Prata sheds light on romantic eroticism:
Q. What led you to Jesus?
A. Beth Moore’s  answer:
My Sunday-school teacher would hold up pictures of Jesus, and he looked so nice. I needed a hero, and Jesus seemed like one. I’d lie on the grass, stare up at the sky, and wonder what Jesus was like. Even as a child, I fell in love with him. After my freshman year in college, I was a camp counselor for sixth-grade girls. Early one morning, as the girls were sleeping, I sensed God’s presence enfold me. There were no audible words, no bright lights. But suddenly I knew, without a doubt, my future was entirely his. You are now mine, he told me. (source)
