What I'll Know Then

Some fools don't know what they've got 'til it's gone
They let true love slip away
But I don't need to lose you to know what I've found
I'll love you 'til my dying day

I know now what I'll know then
A love like yours is Heaven sent
And I'll thank God for you until my life ends
'Cause I know now what I'll know then

The grass will be greenest wherever you are
Your love is a rose that won't fade
And as the years turn golden, our hair turns gray
I'll need you like I do today

I know now what I'll know then
A love like yours is Heaven sent
And I'll thank God for you until my life ends
'Cause I know now what I'll know then
Yes, I'll thank God for you until my life ends
'Cause I know now what I'll know then
