What the Bible says about Doing Good Does Not Signify Sanctification
(From Forerunner Commentary)
Mankind is evil! In this case, Jesus did not use evil to indicate “essential wicked character,” but more along the lines of “given to do acts of wicked conduct,” indicating an inclination. Though unconverted and not specifically sanctified to be created in God's image, a worldly person can on occasion do a good thing. Some uncalled people do them consistently. However, doing some good things now and then does not make an individual good by nature. Thus, doing good does not signify that a person is a called, sanctified, and converted child of God.
