It is the nature of man as the reflection of God to be good and to do good. Nevertheless, from the evil influences apparently rampant in the world today, it would seem that mankind's efforts to be good and to do good are of little avail and that people are often prone to practice that which is not good.
In his Epistle to the Romans, Paul wrote (7:18, 19): "I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. For the good that I would I do not: but the evil which I would not, that I do." Thus Paul exposed the claim of error, or evil, to resist Truth, good. He named the resisting force when he said (8:7), "The carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be."
The carnal mind claims to oppose that which is good. Therefore it would resist every progressive step that one tries to take to gain a clearer concept of good through the study of Christian Science.
