Browning, in his _Abt Vogler_, sings practically the same sweet song
where he says:

Sorrow is hard to bear, and doubt is slow to clear,
Each sufferer says his says, his scheme of the weal and woe:
But God has a few of us whom He whispers in the ear;
The rest may reason and welcome; 'tis we musicians know.

If God whispers in the ear of the sufferer, the doubter, the
distressed, the worried, the peace must come; and if peace come, it
matters not what others' reasoning may bring to them, the knowledge
that God has whispered is enough; it brings satisfaction, content,
serenity, peace. The opposite of worry is rest, faith, trust, peace.
How full the Bible is of promises of rest to those who know and love
God and his ways of right-doing. Mendlessohn took the incitement of
the psalmist (Psalm 37:7), "Rest in the Lord, and wait patiently for
him," and made of it one of the tenderest, sweetest songs of all time.
Full of yearning over the worried, the distressed, the music itself
seems to brood in sympathetic and soothing power, as a mother croons
to her fretful child: "Why fret, why worry,--No, no! rest, rest my
little one, in the love of the all-Father," and many a weary, fretful,
worried heart has found rest and peace while listening to this sweet
and beautiful song.

There is still another passage in holy writ that the perpetual worrier
should read and ponder. It is the prophet Isaiah's assurance that God
says to His children: "As one whom his mother comforteth, so will I
comfort you."
