This is indeed sad, I believe it hasn't been easy going through this experience but in all God knows best. I'm sorry for your loss. God works in ways we cannot see and sometimes it very hard to know what He's up to. The only thing we can do is to keep trusting Him even if we going through the worse. I believe He wait till the last minute when we cannot carry on then He steps in so we will understand that He is the God of possibilities and He iscapable of turning things around even at the last minute.
