Why is it that when the Word of God clearly states:
Matthew 7:18-20 (King James Version)
(18) A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. (19) Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. (20)
Wherefore by their fruits ye shall know them.
that we will know people by their fruits that most Christians change it to "we will know them by their doctrine?"
