Christian confidence and stability

I build my house upon a rock,--
Faith's strong foundation firm and sure,
My fix'd abode the heaviest shock
Of time and tempest to endure.

Not small, nor large, not low, nor high,
Midway it stands upon the steep,
Beneath the storm-mark of the sky,
Above the flood-work of the deep.

And here I humbly wait whilst He
Who pluck'd me from the lowest hell,
Prepares a heavenly house for me,
Then calls me home with Him to dwell.
