Isaac Watts was a pastor and hymn-writer of the late 1600's and early 1700's in England. He is quite
well-known for his hymns in the western world today, but back in his days he was probably more well-known as a logician. He was the author of a very popular textbook on Logic. Along with John Newton, Watts is one of my favorite hymn writers.
Most of Watts' hymns are taken right out of the Scriptures and that is definitely the case with the one below. It is based primarily on Isaiah 27-30, along with a clear reference to Isaiah 40 at the end.
1) Whence do our mournful thoughts arise? And where's our courage fled?
Have restless sin and raging hell Struck all our comforts dead?
2) Have we forgot th' almighty name That form'd the earth and sea?
And can an all-creating arm Grow weary or decay?
3) Treasures of everlasting might In our Jehovah dwell:
He gives the conquest to the weak And treads their foes to hell.
4) Mere mortal power shall fade and die, And youthful vigour cease;
But we that wait upon the Lord Shall feel our strength increase.
5) The saints shall mount on eagles' wings, And taste the promis'd bliss,
Till their unwearied feet arrive Where perfect pleasure is.
