Listening to every heart
Kristen...it is so hard for us to let go. But your friend's father sounds as if he has his own thoughts and feelings together and sure about what is left for him to enjoy, and what, perhaps, he can look forward to. It is the "not knowing" that is scariest; and the loss that we will feel after someone we care deeply for, is gone.
In addition to your prayers for this wonderful man, he needs most your daily presence as you can give it to him; to let him know that you are there to mark this final stage with him, and to add some balance to the new upheaval.
You are loving, and compassionate. I know you will be there for him, and the rest of the family, all the way through. So I will join you in your prayers.
