From our Articles of Faith
3 We believe that through the Atonement of Christ, all mankind may be saved, by obedience to the laws and ordinances of the Gospel.
4 We believe that the first principles and ordinances of the Gospel are: first, Faith in the Lord Jesus Christ; second,Repentance; third, Baptism by immersion for the remission of sins; fourth, Laying on of hands for the gift of the Holy Ghost.
Now all that is in line with Act 3 and Peter's answer given to the new converts.
You said; "...rather will be the natural outcome of a true repentance..."
Yes that is the goal, that doing good and choosing not to sin becomes a natural part of our daily life. There were those in the Lord's parable who when told they fed the Lord they were puzzled and ask when did we do that? It was just something they did naturally. The others in the parable did not feed the hungry and they were condemned " these shall go away into everlasting punishment: but the righteous into life eternal." Matt 25
James tells us "Therefore to him that knoweth to do good, and doeth it not, to him it is sin"
Of all people Christians should know what good is but not always, temptations are put before us and we must with the help of the Holy Spirit choose the good. If we falter there is always the door of repentance, of starting over and moving forward. It's a progression of sanctification, we overcome the flesh's desire to sin.
What the real difference between us is, is that we believe a man can fall from grace through sin and most Evangelicals don't.
In Matt 5 the Lord sets down the New Covenant's laws;
For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
He explained the old law was dead and a new one expanding the law was now being set in place.
21 ¶Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:
22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
That may seem like a given today but at the time of Jesus that was a whole new level of thought and it had to be taught to them. Each new Christian needs to be taught also and it doesn't hurt for us to be reminded.
" And whosoever shall compel thee to go a mile, go with him twain"
That's a lot to comprehend and then to adjusts the attitude. In the middle of the Lord's prayer he says
" And forgive us our debts, as we forgive our debtors."
and then adds
14 For if ye forgive men their trespasses, your heavenly Father will also forgive you:
15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
He said in his be-attitudes
"Blessed are the merciful: for they shall obtain mercy"
If our hearts can not learn forgiveness of others, if we can not learn charity for others all the faith in the world isn't going to save us.
*But back to Elder Scott's talk and his actual intent. Brother Scott wasn't talking just about salvation in the next life but finding peace in this life. He was comparing life to rock climbing and he compared the laws of God to the anchors a rock climber uses.
"In real life, the anchors are the laws of God that provide protection under all of the challenges that you will face. The rope and carabiners that secure the rope to the anchors represent obedience to those commandments. When you learn those commandments, continue to practice them, and have a plan to avoid danger, you will have a secure means of obtaining protection against Satan’s temptations. You will develop strength of character that will fortify you against transgression. Should you make a wrong move, there need be no enduring problem because of the belaying or help that is available through your repentance.
.......
The Redeemer will safely lead you over the most difficult obstacles of life. His laws are absolutely secure anchors of protection that dispel fear and assure success in an otherwise dangerous world. Such a life will certainly provide you peace and happiness."
Then he talks about the Atonement and this explains phobe's question and it really is about consequences for actions.
"Each of us makes mistakes in life. They result in broken eternal laws.(like thou shalt not lie) Justice is that part of Father in Heaven’s plan of happiness that maintains order. It is like gravity to a rock climber, ever present. It is a friend if eternal laws are observed. It responds to your detriment if they are ignored. Justice guarantees that you will receive the blessings you earn for obeying the laws of God. Justice also requires that every broken law be satisfied. When you obey the laws of God, you are blessed,
but there is no additional credit earned that can be saved to satisfy the laws that you break. If not resolved, broken laws can cause your life to be miserable and would keep you from returning to God. Only the life, teachings, and particularly the Atonement of Jesus Christ can release you from this otherwise impossible predicament.
The demands of justice for broken law (thou shalt not lie) can be satisfied through mercy, earned by your continual repentance and obedience to the laws of God. Such repentance and obedience are absolutely essential for the Atonement to work its complete miracle in your life. The Redeemer can settle your individual account with justice and grant
forgiveness through the merciful path of your repentance. Through the Atonement you can live in a world where justice assures that you will retain what you earn by obedience. Through His mercy you can resolve the consequences of broken laws."
Okay I lied about something, I can not go out and feed the poor more and expect I'm being forgiven of that lie if I don't repent of it. I have to go to the Lord and say I lied please forgive me and help me not to lie again. Then as I continue not to lie the Lord's mercy takes effect and I'm forgiven. However if I continue to lie then the Lord will not forgive me, I have to truly repent.
Now since I've learned not to lie people begin to trust me and I have a happier life in general and I don't have to suffer for the sin of lying in the next life. Repentance is a major part of being obedient, it's not about counting up brownie points but about making changes to your life so we walk more Christ like.
what we are talking about when we say " what you earn by obedience" we mean peace in your life. There is also the reward in the eternities
"But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God; Who will render to every man according to his deeds: To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life" Rom 2
I like the "patient continuance" it means it doesn't happen all at once but over time. I'd say 99% of the people who live on this earth do some good at some point, that good is not forgotten by justice. Each will receive a reward for the good which they did no mater how small.
