Sister’s Heart Returning to Jesus and Truth — Giana

I need prayer for my sister, she was on fire for God something changed her, now she says she's not a believer, and that she is only a Israelite,and no long calls God God. I wish that she could come back and believe that Jesus is the truth. And remember what God did for her, anyway please send me and prayer to Stand on, this is really needed I don't want her to try to get to any other family members of mine. I thank for the prayers ahead by faith I believe God can change her back. Ms GI
