Dear Milo,
Make her question if the love of the Enemy is relevant in her day to day life. Make her doubt that the love of God is ALL that she needs, every day. This is really quite simple since she lives in a world inundated by messages that say she needs this, needs that, must attain this quality or this item in order to succeed. When she feels some lack, let her turn to a myriad of other things instead of the Enemy. She doesn’t know that it isn’t so much an empty void that disturbs her, but what she turns to for filling that void. Keep her running on various other fuels like attention, analyzation, self-improvement, social interaction, and let her exhaust her other options before turning to the Enemy.
