I once attended the funeral of a young girl who had died of leukemia. She was a beautiful, intelligent homeschooled teenager who had so much promise. But her family were atheists and her funeral was so full of secular readings, etc., and nothing of faith or hope or even eternal life. This couple had no comfort, had no faith or even hope of seeing their loved one again. It was the saddest funeral I’ve ever seen because it was devoid of hope. The parents are now divorced.
Around the same time, a young girl near us, Sarah Ann Wood, was kidnapped and murdered. They have never recovered her body. But her parents were able to go through this praising God in spite of it all. He was a pastor and they both had a great relationship with their Lord. They KNOW they will see their child again. That’s the difference.
