Hymn Lyrics Search - Name That Hymn

please help me find this song..... it was my grannys favorite and i would really appreciate any help GOD BLESS

What makes a dying saint lift up her hands
And thank God for all the years she was able to stand
Then with a weary sigh a far-away look in her eye
She begins to say this prayer as if she's almost there

Lord put a white robe around me
and give me a crown to wear
Let me take your hand let me understand its forever
Then lead me to my promise land

So if I stumble on life's shifting sands
Just reach out Lord let me take hold of your hand
For the mountains are tall and the road is oh so rough
Just one glimpse of my promise land will be enough

How does the tune go please
