Old Adam put in a better dress

(Thomas Watson, "A New Creature")

"I tell you the truth, no one can see the kingdom
 of God unless he is born again." John 3:3

Natural honesty, moral virtue, prudence, justice, liberality,
temperance--these are not the new birth. These make a
glorious show in the eye of the world—but differ as much
from the new birth, as a stick differs from a star! Morality
indeed is commendable, and it would be well if there were
more of it. Yet morality is but nature at its best; it does not
amount to saving grace. There is nothing of Christ in morality.
That fruit is sour--which does not grow on the root of Christ!

Heat water to the highest degree--and you still cannot
make wine out of it; it is water still. Just so, let morality
be raised to the highest, it is nature still; it is but old
Adam put in a better dress.

Moral virtue may exist with the hatred of godliness.
A moral man hates holiness--as much as he does vice!

"You must be born again." John 3:7
