know who is near you. Sing, perhaps you will get a companion by it.
Sing! perhaps there will be many a heart cheered by your song. There
is some broken spirit, it may be, that will be bound up by your
sonnets. Sing! there is some poor distrest brother, perhaps, shut up
in the Castle of Despair, who, like King Richard, will hear your song
inside the walls, and sing to you again, and you may be the means of
getting him a ransom. Sing, Christian, wherever you go; try, if you
can, to wash your face every morning in a bath of praise. When you go
down from your chamber, never go to look on man till you have first
looked on your God; and when you have looked on Him, seek to come down
with a face beaming with joy; carry a smile, for you will cheer up
many a poor way-worn pilgrim by it.

One more reason; and I know it will be a good one for you. Try and
sing in the night, Christian, for that is one of the best arguments in
all the world in favor of your religion. Our divines nowadays spend a
great deal of time in trying to prove Christianity against those who
disbelieve it. I should like to have seen Paul trying that! Elymas the
sorcerer withstood him: how did our friend Paul treat him? He said,
"Oh, full of all subtlety and all mischief, thou child of the devil,
thou enemy of the righteousness, wilt thou not cease to pervert the
right ways of the Lord?" That is about the politeness such men ought
to have who deny God's truth. "We start with this assumption: we will
prove that the Bible is God's word, but we are not going to prove
God's word. If you do not like to believe it, we will shake hands, and
bid you good-by; we will not argue with you. The gospel has gained
little by discussion. The greatest piece of folly on earth has been
to send a man round the country, to follow another up who has been
lecturing on infidelity just to make himself notorious.
