What To Say To Someone When They Say They Lost A Family Member?

What do you say to someone that lost a family member/     means you're right there on the phone call you have to make as soon as possible or you know you will meet them in person, as soon as possible.  If it's much later because you are not able to do either that's ok too.  (HAVE YOUR PHONE NO. ON A NOTE/PIECE OF PAPER TO PASS OFF IN THEIR HAND)        SO I might say something like this and/or combination.  Just say one sentence, with the sincerity and focus you're feeling now in your heart...
*I am so sad for you;  your family and you have been heavy on my heart.    
* I've had you and your family on my mind since your loss.  I'm your friend, please call me...    
* I've really been thinking and praying about you and your family.
*  Heavy on my mind your whole family, God bless,
*   My church group is praying for you and your family.  
*   I'm praying for your family and you.  Remember, you can call me anytime.
*    Hey, call anytime. I've  been praying and thinking about you and your family so much.
******Remember;  have your number on the note ready to grab their hand and set it in.   I wouldn't say call me if you don't have that number in your hand ready to pass on over to theirs.
