I am so sorry about your mom. That’s great that she’s getting to take that trip. I’m sure it will be a real blessing to her to walk where Jesus walked and lived as a man and changed history forever. Always wanted to do that myself. Just take things one day at time, continue to pray for her and trust her to God. I know how hard that can be though. His ways are not our ways, and He doesn’t seem to feel compelled to explain Himself to us a lot of the time.
May God bless you!
