Exodus 17:7: Not all the miracles of love

Not all the miracles of love
Which Thou hast wrought for me
Can out of this base heart remove
Its incredulity:
One hour without the sweets of grace
In peevish haste I mourn,
"The Lord hath left me in distress,
And never will return."
vol. IX. E

But, O Thou patient God, forgive
A murmuring Israelite
And learn me how to wait and grieve
When Thou art out of sight;
By dryness tried, and want, and pain,
I fain in Thee would trust.
Most present with Thy people then
When Thou chastisest most.
