"Behold, he prays."  Acts 9:11

(adapted from Spurgeon)

Prayers are instantly noticed in heaven.

The moment Saul  began to pray the Lord
heard him. Here is comfort for the distressed,
but praying soul.  Oftentimes a poor broken
hearted one bends his knee, but can only
utter his wailing in the language of sighs
and tears; yet that groan has made all the
harps of heaven thrill with music; that tear
has been caught by God and treasured in
the lachrymatory of heaven. "You put my
tears into your bottle," implies that they
are caught as they flow.

The suppliant, whose fears prevent his words,
will be well understood by the Most High.
He may only look up with misty eye; but
"prayer is the falling of a tear."

Tears are the diamonds of heaven!

Sighs are a part of the music of Jehovah's
court, and are numbered with "the most
sublime strains that reach the majesty
on high."

Think not that your prayer, however weak
  or trembling, will be unregarded.

Our God not only hears prayer but also loves
to hear it. "He forgets not the cry of the humble."
True, He regards not high looks and lofty words;
He cares not for the pomp and pageantry of kings;
He listens not to the swell of martial music;
He regards not the triumph and pride of man;
but wherever there is a heart big with sorrow,
or a lip quivering with agony, or a deep groan,
or a penitential sigh, the heart of Jehovah is open;
He marks it down in the registry of His memory.
He puts our prayers, like rose leaves, between
the pages of His book of remembrance, and when
the volume is opened at last, there shall be a
precious fragrance springing up therefrom.
