Reasoning with God

Hidden Lord, most wise and rich,
Whom oft I love, but often fear;
Of light and dark, oft doubting which,
Doth most upon Thy works appear:
Why, if in Thee no darkness is,
So deep a shade on human kind?
If Thou be Father, tell me this.
Why the sad heart, the troubled mind?
Then said a voice, " This truth within thee store,
And wait, believing, ere thou askest more:
Earth is a cloud which Time shall put away.
Then shalt thou see the heaven and feel the day."
