Lyrics:

Faith is such a mystery
To lean on something you can't see
It's a rock our love was built upon
Oh, and it's strong enough to rely on

Faith in you is why I sing
Trust is quite another thing
It took some time but finally learned
Oh that it ain't no gift it's gotta be earned

If there's only one gift from God above
It's honest faithful trusting love
It's in your heart which I adore
