Bible study gone wrong: Inspired by a church sermon on the Book of Genesis, a Florida woman allegedly killed a 2-year-old girl and attempted to kill the girl’s 10-year-old brother in a failed attempt to recreate the Biblical story of Abraham.

According to police, Kymberley Dawn Lucas, 40, is accused of killing 2-year-old Elliana and trying to kill her 10-year-old brother Ethan before trying, unsuccessfully, to end her own life.

Lucas and her longtime partner had raised the boy and girl since their birth.

Investigators report Lucas attended a sermon by Metropolitan Community Church pastor Lea Brown this past Sunday. Brown’s sermon covered the Biblical story of Abraham attempting to sacrifice his son Isaac on orders from God, only to be stopped by God at the last minute.

Pastor Brown says she stands by her sermon on Abraham, saying “It’s what I was called to do, there’s no way anyone could have predicted this.”

Brown confirmed that the children and both women attended her service, and that her sermon covered Genesis 22, in which God challenges Abraham to sacrifice his son Isaac.

In the Biblical account, Abraham follows God’s instructions, taking the boy to a mountain, laying Isaac on an altar in preparation for the sacrifice. At the last second, God orders Abraham to spare the child.

In a suicide note Lucas reports that unlike the Biblical account of Abraham, God did not step in and stop her from taking the child’s life. An excerpt from the note reads:

“Lea’s sermon really, really touched me yesterday but God never told me to stop!”

Lucas is being held at the Palm Beach County Jail and faces charges of first-degree murder and attempted first-degree murder.
