the hymn: "now thank we all our God"

See lyric below...

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

Is this lyric suggesting that we will have ills in the next life? either way, if hymns give us our theology this is a cautionary example.

i can't rag on the hymn writer considering the following facts:

Martin Rinkart (1586-1649) wrote the hymn...

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.
