Once a man or a woman takes to the popular notion that the purpose of the atonement is, one way or another, to bring about a gospel which is not particularly different than the false teachings warned about in the scripture.
2 Nephi 28:7 Yea, and there shall be many which shall say: Eat, drink, and be merry, for tomorrow we die; and it shall be well with us.
8 And there shall also be many which shall say: Eat, drink, and be merry; nevertheless, fear God—he will justify in committing a little sin; yea, lie a little, take the advantage of one because of his words, dig a pit for thy neighbor; there is no harm in this; and do all these things, for tomorrow we die; and if it so be that we are guilty, God will beat us with a few stripes, and at last we shall be saved in the kingdom of God.
It seems practically impossible to separate them from the notion. They file this misconception under the name "grace" and then it becomes a herculean task to convince them that is not what grace is about in the least, nor was the atonement made so that God could "justify in committing a little sin".
We read in D&C 93 that the Savior progressed from grace to grace until he received a fulness of grace. If grace means a divinely endowed ability to sin to one degree or another without suffering the consequences then those scriptures are puzzling indeed. If that is what grace is, then as we progress we should require less of it, having less of an inclination toward doing wrong, not more of it until we receive a fulness of it.
But that isn't what the word grace means at all in the scriptures. That is an apostate notion first put forth by Martin Luther. It has been popularized among us by Stephen Robinson's book "Believing Christ" and continues to be taught by those who followed him.
