An Anchor At Sea

Grace is of the greatest and sweetest use to the soul.
It is an anchor at sea, and a shield at land. Grace is a
staff to uphold the soul, and a sword to defend the soul.
Grace is bread to strengthen the soul, and wine to cheer
the soul. Grace is medicine to cure all diseases, and a
plaster to heal all wounds, and a cordial to strengthen
the soul under all faintings, etc. Grace is . . .
  your eye to see for Christ,
  your ear to hear for Christ,
  your head to design for Christ,
  your tongue to speak for Christ,
  your hand to do for Christ, and
  your feet to walk with Christ.

- Thomas Brooks, "The Unsearchable Riches of Christ"
