It was quite a shock to me that my little sister came to the Lord. I always thought she was too hard-headed to submit. I'm glad I was wrong!
To you and anyone else that has lost loved ones, I'd like to share an article with you. I read this article about 2 weeks before my sister got shaken up and drawn by God. Perhaps the article had a nugget of wisdom that helped. Try it for yourself and see if you get similar results?
