Thanksgiving Deferred

I bless Thee, Lord, who hast restored my sight;
Where were my thanks through all my years of light?
Thou liftest me again; Thy praise I tell;
Where was my gratitude before I fell?
Thou healest me; glad thanks to Thee belong;
Alas, my thankless heart when I was strong!
My fetters Thou dost loose; all praise to Thee!
And yet I praised Thee not when I was free.
I bless Thee, who dost all my ills remove;
But ah, when all was well, where was my love?
