The ship of prayer!
Spurgeon, "Memory -the Handmaid of Hope"
In all states of dilemma or of difficulty,
prayer is an available source.
The ship of prayer may sail through all
temptations, doubts and fears, straight
up to the throne of God; and though
she may be outward bound with only
griefs, and groans, and sighs, she shall
return freighted with a wealth of blessings!
