Looking for the lyrics to this song, I used to hear it on the radio regularly but have not heard it in years and cannot find it online except for a low quality clip that just has a few lines from a verse and the chorus.

“… For one thing my God he was pleased,
That I staggered not at his promise…
The promise of his victory.

Chorus:
I stagger not at Gods holy promise,
I stagger not, I’m fully persuaded.
I stagger not and there’s no room for doubt,
I staggered not when he called me out.”
