Many people are working and working, as Rowland Hill said, like
children on a rocking-horse--it is a beautiful motion, but there is no
progress. Those who are working for salvation are like men on a
treadmill, going round and round and round; toiling and toiling and
toiling; but nothing comes of it all. There is no progress, and there
cannot be until you have the motive power within, till the breath of
life comes from God, which can alone give you power to work for
others.
