The fruit does not make the tree good or bad but the tree itself is what determines the nature of the fruit. In the same way, a person first must be good or bad before doing a good or bad work.
Whenever the word is rightly preached, and attentively heard, it never fails to bring forth fruit.
There is no justification without sanctification, no forgiveness without renewal of life, no real faith from which the fruits of new obedience do not grow.
