In the anonymous Old English poem Beowulf, how does Beowulf feel his life was saved? (See lines 1651-1887 of the Seamus Heaney translation)

In lines 1651-1887 of the Seamus Heaney translation of the
Old English epic poem Beowulf, Beowulf offers several reasons why
his life was saved in his battle with Grendel’s mother.  His description of his fight
with her includes the following elements:

• He
  acknowledges that the battle was

. . . hard-fought, a desperate
affair

that could have gone badly; if God had not helped
me,

the outcome would have been quick and fatal.
(1656-58)

He thus
acknowledges his utter dependence on God and gives God the glory for the
victory.

• He acknowledges the insufficiency of
  his own strength and weaponry and thus credits God with his victory
  (1659-1661).


• He gives God credit for allowing him to spot
  a useful weapon (1661-64).


• He indicates that, having
  received help from God, he then conducted himself wisely and bravely, although he
  doesn’t boast (1665-66). He thus shows that God helps those who try to help themselves,
  especially if their causes is virtuous and just.


• He
  offers his victory as a gift to Hrothgar and the Danes
  (1671-76).


• He shows respect to Hrothgar by giving
  Hrothgar what is left of the weapon used to slay Grendel’s mother (1677-79).
  

In short, Beowulf speaks precisely as an ideal
early Christian warrior should speak: he glorifies God; he shows respect to those above
him on the “great chain of being”; he is modest; he is brave, he is eloquent; he is
wise; he acknowledges the power of earthly evil while also paying tribute to the greater
power of God; he sees himself as an instrument of God’s providence; and he conducts
himself with dignity, humility, sincerity, and prudence.
