A sad time

Tonight is sad for us. Mark's step sister Leslie passed away this afternoon. Leslie was 38 and a wife and mom to 5 kids. She died of breast cancer.
I apologize to those of you that already have this background info- but for the rest I'm going back a bit...
Leslie and her husband got sucked into a cultish religion a few years back. They didn't believe in Dr's. She found a breast lump a couple years ago and did nothing. At the end of last year she completely collapsed and they ended up taking her in an ambulance to the Dr. She would only get pain meds and at that time she only had 1 rib left- the cancer had completely eaten away the other rib. It was only at that time that the family found out about her cancer. Don (Mark's step dad) and Mark's mom tried over and over again to get her to see the truth about this cult but she would have none of it. The really sad thing is that she was brought up in a Christian home and just turned her back on the truth. We have been praying for her and her family but never saw any changes in their thinking. This past week she was pretty much out of it and was unresponsive when Don and Mom spoke to her. However when they would read the Bible to her she would start crying. It is our prayer that somehow God touched her heart at the end and she is in Heaven without pain and with a healed body. Please pray for her family. The kids are ages 5-16 and at the end she didn't recognize the youngest one and didn't want her to be around her. Please lift our whole extended family up- especially Don. After Mark's dad died we feel so blessed to have him in our lives he is such a sweet man and has already suffered the loss of his wife years ago and this is really taking a toll.
The funeral will be Tuesday- I don't know what to expect at all so please pray that God will give me the right words to say.
