There are many versions of Wade In The Water or God Gonna Trouble The Water. Here is one from Alabama.

GOD GONNA TROUBLE THE WATER

Chorus
I'm er wadin', I'm er wadin' in the water, chillun (3 times)
God gonna trouble the water.

Oh, Satan is er liar en er conjurer too,
God gonna trouble the water,
Ef you don't watch out he'll conjure you,
God gonna trouble the water.

I 'members the day, I 'members hit well,
God gonna trouble the water,
When Jesus freed my soul from hell,
God gonna trouble the water.

Chorus

One day, one day I went out to pray,
God gonna trouble the water,
My soul got happy en I stayed all day,
God gonna trouble the water.

Ole Satan mad en I am glad,
God gonna trouble the water,
He missed er soul he thought he had,
God gonna trouble the water.

To "wade in the water" is to undergo the spiritual regeneration symbolized by baptism. "The migratory Satan stanzas may appear to bear ...no relationship...to the theme of rebirth, but rebirth frees the soul from the sin that Satan personifies. "Got happy" is a Southern folk expression for the religious ecstasy of conversion or other transcendent experience."
Olivia and Jack Solomon, "Honey In The Rock," The Ruby Pickens Tartt Collection, 1991, p. 10.
