Oh! say, but I'm glad

There is a song in my heart today,
Something I never had;
Jesus has taken my sins away,
O say, but I'm glad!

Refrain
O say, but I'm glad, I'm glad,
O say, but I'm glad!
Jesus has come and my cup's overrun,
O say, but I'm glad!

Wonderful, marvelous love He brings,
Into a heart that's sad;
Thru darkest tunnels the soul just sings,
O say, but I'm glad!

Won't you come to Him with all your care,
Weary and worn and sad?
You, too, will sing as His love you share,
O say, but I'm glad!
