Analysis of Renewal of Strength

The prison-house in which I live
Is falling to decay,
But God renews my spirit's strength,
Within these walls of clay.

For me a dimness slowly creeps
Around earth's fairest light,
But heaven grows clearer to my view,
And fairer to my sight.

It may be earth's sweet harmonies
Are duller to my ear,
But music from my Father's house
Begins to float more near.

Then let the pillars of my home
Crumble and fall away;
Lo, God's dear love within my soul
Renews it day by day.
