Was a guest and a stranger here;

That we might live eternally,

All this did he for us freely,                                                                                                                                                                            
For to declare his great mercy;                                                                                                                                                                           
All Christendom be merry therefore,                                                                                                                                                                       
And give him thanks for evermore,
