Satan begins by producing distrust in God, and so stirring man’s will into activity in lust and disobedience. Never does the enemy lead one to think of the goodness of God nor of man’s obedience. The woman knew right well that she ought not to eat of the tree and that mischief must be the result; yet she ate and gave to her husband with her, and he did eat (Gen. 3:1-6). Thus sin is the self-will that sprang from the unbelief which doubted God. By this means Satan made a breach; he persuaded Eve that God kept something for Himself, for fear that His creature should be too happy and too blessed. But Eve was wrong in listening to Satan; she ought not for a moment to have attended to the voice which insinuated distrust in God.
