here are the words i sing.
i have a recording from maybe the 30's by The new Bethel Baptist Church Choir and have heard numerous recordings including one by Marion Anderson.

refrain:
i've been in the storm so long x3
Just give me a little time to pray

verse 1:
Let me tell you, mother, how i come along
..give me some time to pray..
With a hung-down head and an aching heart
...give me a little time to pray

~refrain~

verse 2:
When i get to heaven i'm gonna take my seat,
..give me some time to pray..
Gonna cast my crown at my Jesus' feet
..give me a little time to pray

~refrain~

verse 3:
When i get to heaven, i'm gonna walk all about,
...give me some time to pray..
Ain't nobody here gonna turn me out
..give me a little time to pray

~refrain~
