This song has been running through my mind during the past few days. May I ever thank our eternal God with my heart and hands and voice.

Now thank we all our God, with heart and hands and voices,
Who wondrous things has done, in Whom this world rejoices;
Who from our mothers’ arms has blessed us on our way
With countless gifts of love, and still is ours today.

O may this bounteous God through all our life be near us,
With ever joyful hearts and blessèd peace to cheer us;
And keep us in His grace, and guide us when perplexed;
And free us from all ills, in this world and the next!

All praise and thanks to God the Father now be given;
The Son and Him Who reigns with Them in highest Heaven;
The one eternal God, Whom earth and Heaven adore;
For thus it was, is now, and shall be evermore.

Martin Rinkart, 1636; Translated by Catherine Winkworth, 1858
Cyberhymnal gives the story behind this hymn:

Martin Rinkart, a Lu­ther­an min­is­ter, was in Eil­en­burg, Sax­o­ny, dur­ing the Thir­ty Years’ War. The walled ci­ty of Eil­en­burg saw a stea­dy stream of re­fu­gees pour through its gates. The Swed­ish ar­my sur­round­ed the ci­ty, and fa­mine and plague were ramp­ant. Eight hund­red homes were de­stroyed, and the peo­ple be­gan to per­ish. There was a tre­men­dous strain on the pas­tors who had to con­duct do­zens of fun­er­als dai­ly. Fi­nal­ly, the pas­tors, too, suc­cumbed, and Rink­art was the on­ly one left—doing 50 fun­er­als a day. When the Swedes de­mand­ed a huge ran­som, Rink­art left the safe­ty of the walls to plead for mer­cy. The Swed­ish com­mand­er, im­pressed by his faith and cour­age, low­ered his de­mands. Soon af­ter­ward, the Thir­ty Years’ War end­ed, and Rinkart wrote this hymn for a grand cel­e­bra­tion ser­vice. It is a test­a­ment to his faith that, af­ter such mis­e­ry, he was able to write a hymn of abid­ing trust and gra­ti­tude to­ward God.
