You apparently aren't getting it:
Mormonism teaches an examplier Jesus while stressing obedience to the commandments … that leads only to a tragic result of being condemned to outer darkness because of failure to obey 100%.
Biblical Christianity teaches a substitute Jesus, were God declares Jesus' perfect obedience to the commandments is being credited to us through faith in that alone … that is the saving gospel.
We also believe in the atonement and that through the atonement that all mankind may be saved. But we can not reject obedience to the laws and ordinances of the gospel. The Bible does not endorse sin even to the least degree. It is sin that separates us from God. Even the act of not helping someone is sin. Consider of what happened to the rich man in the story about Lazarus:
(New Testament | Luke 16:19 - 31)
19 ¶ There was a certain rich man, which was clothed in purple and fine linen, and fared sumptuously every day:
20 And there was a certain beggar named Lazarus, which was laid at his gate, full of sores,
21
And desiring to be fed with the crumbs which fell from the rich man's table: moreover the dogs came and licked his sores.
22 And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried;
23
And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom.
24 And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame.
25 But Abraham said, Son, remember that thou in thy lifetime receivedst thy good things, and likewise Lazarus evil things: but now he is comforted, and thou art tormented.
26 And beside all this, between us and you there is a great gulf fixed: so that they which would pass from hence to you cannot; neither can they pass to us, that would come from thence.
27 Then he said, I pray thee therefore, father, that thou wouldest send him to my father's house:
28
For I have five brethren; that he may testify unto them, lest they also come into this place of torment.
29 Abraham saith unto him, They have Moses and the prophets; let them hear them.
30 And he said, Nay, father Abraham: but
if one went unto them from the dead, they will repent.
31 And he said unto him, If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead.
Jesus is our example:
(New Testament | 1 John 2:3 - 6)
3 And hereby we do know that we know him, if we keep his commandments.
4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
6
He that saith he abideth in him ought himself also so to walk, even as he walked.
