Lyrics:

How long would it take to count all the stars
How long would it take to climb up to Mars
How long has this old world stood so true
Well, that's how long it'd take me to stop loving you

How long has the sea had water so deep
How long has the mountain stood so steep
How long has it been since this world was new
Well, that's how long it'll take me to stop loving you

How long is forever and a day
How old is time dear, can you say
How long has God's love been so true
Well, that's how long it would take me to stop loving you
