1 Have you not known, have you not heard
that firm remains on high
the everlasting throne of him
who formed the earth and sky?
2 Are you afraid his pow'r shall fail
when comes thine evil day?
And can an all-creating arm
grow weary or decay?
3 Supreme in wisdom as in pow'r
the Rock of Ages stands,
though him you cannot see, nor trace
the working of his hands.
4 He gives the conquest to the weak,
supports the fainting heart;
and courage in the evil hour
his heav'nly aids impart.
5 Mere human pow'r shall fast decay,
and youthful vigor cease;
but they who wait upon the Lord
in strength shall still increase.
6 They with unwearied feet shall tread
the path of life divine;
with growing ardor onward move,
with growing brightness shine.
7 On eagles' wings they mount, they soar -
their wings are faith and love -
till, past the cloudy regions here,
they rise to heav'n above.
