Loosing a loved one but knowing of a future reunion can be bitter but sweet. I'll try and post some lyrics to a good song that speak of a similar situation. Prayers to you and your family. Sorry, as of right now I only have this copy that has the chords that are tab style. I'll post it later without chords. It's a great song by Western music artist R.W. Hampton.
I still have both my parents, healthy at 89 and 92. I know I'll face what you are going thru one day and I know there will be great sadness but also great joy knowing I'll see them again.
What a comfort Jesus is to us during a difficult time.
May God bless and keep you and your family now and for the days ahead.
