Oh God, our help in ages past

1059 C. M.
Man frail — God eternal.

O GOD, our help in ages past,
   Our hope for years to come,
   Our shelter from the stormy blast,
   And our eternal home:—

2 Under the shadow of thy throne
   Still may we dwell secure;
   Sufficient is thine arm alone,
   And our defence is sure.

3 Before the hills in order stood,
   Or earth received her frame,
   From everlasting thou art God,
   To endless years the same.

4 A thousand ages, in thy sight,
   Are like an evening gone;
   Short as the watch that ends the night,
   Before the rising sun.

5 Time, like an ever-rolling stream,
   Bears all its sons away;
   They fly, forgotten, as a dream
   Dies at the opening day.

6 The busy tribes of flesh and blood,
   With all their cares and fears,
   Are carried downward by the flood,
   And lost in foll’wing years.

7 O God, our help in ages past,
   Our hope for years to come;
   Be thou our guide while life shall last,
   And our perpetual home!
                         Isaac Watts
                         Methodist Episcopal hymnal (1870 edition)

<idle musing>
This one's a good bit more optimistic than the last one, isn't it? They say that Watts was subject to bouts of depression. I would say he wrote the last one during a bought of depression and this one on one of his better days.
