Necessity of Divine Illumination

"But the natural man receiveth not the things of the Spirit of God; for they are foolishness unto him; neither can he know them, because they are spiritually discerned." — 1 Cor. 2.14.

Oh, send one ray into my sightless ball,
Transmit one beam into my darkened heart!
On Thee, Almighty God, on Thee I call,
Incline thy listening ear, thine aid impart!
In vain the natural sun his beams doth yield,
In vain the moon illumes the fields of air;
The eye-sight of my soul is quenched and sealed,
And what is other light, if shades are there!
Beyond the sun and moon I lift my gaze,
Where round thy throne a purer light is spread,
Where seraphs fill their urns from that bright blaze,
And angels' souls with holy fires are fed.
Oh, send from that pure fount one quickening ray,
And change these inward shades to bright and glorious day.
