Heavenly dew

(J. C. Philpot, "The Doctrine which Drops as the
Rain, and the Speech which Distills as the Dew")

"My words descend like dew."  Deuteronomy 32:2

The dew falls imperceptibly. No man can see it fall.
Yet its effects are visible in the morning. So it is with
the blessing of God upon His Word. It penetrates the
heart without noise; it sinks deep into the conscience
without anything visible going on. And as the dew
opens the pores of the earth and refreshes the ground
after the heat of a burning day, making vegetation lift
up its drooping head, so it is with the blessing of God
resting upon the soul.

Heavenly dew comes imperceptibly, falls quietly, and is
manifested chiefly by its effects, as softening, opening,
penetrating, and secretly causing every grace of the Spirit
to lift up its drooping head.

Whenever the Lord may have been pleased to bless our
souls, either in hearing, in reading, or in private meditation,
have not these been some of the effects? Silent, quiet,
imperceptible, yet producing an evident impression . . .
  softening the heart when hard,
  refreshing it when dry,
  melting it when obdurate,
  secretly keeping the soul alive, so that it is neither withers
up by the burning sun of temptation, nor dies for lack of grace.

"May God give you the dew of heaven." Genesis 27:28
