When I was a child I remember singing this in church but when I ask around now, no one seems to remember it.

It goes something along the lines of this....

Oh Lord Sent the Power Just Now
Oh Lord Sent the Power Just Now
Oh Lord Send the Power Just Now
and Baptised Everyone....

Im not sure of the "correct" name or the lyrics of the whole song, but what I do know is:

I'm going home to Jesus,
In a twinkling of an eye.
I made my reservation,
for a mansion in the sky.

Any help?
