I'm currently (very behind) doing a bible study called:
"Missing Pieces, real hope when life doesn't make sense"
By Jennifer Rothschild
It's all about understanding why God does or doesn't do things in your life and understanding why his plan is the way it is. I'm really loving it because I'm in the same boat as you sister! Fitting God into your life now that it's been drastically turned upside down post college and everything has changed and not knowing how God changes with you is very confusing! But this study is really good at helping you understand Gods reasoning and fairness and how he goes in and fills in those missing pieces in your faith that seem to form whenever you face hardships.
I'm really loving it! It's very enlightening and she writes in a really simple way.
There's also the daily devotional called "streams in the desert for graduates" I read it from time to time and it always has such beautiful messages that seem to relate perfectly to what I need!
If anyone else has any other good books let me know because I'll be in need of a new one after I finish this one!!
Miss y'all and love y'all and praying for y'all!!!
