If the Gospel of Jesus Christ is not action oriented, then please explain the words and counsel of the Lord Himself:
Matthew 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
19 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
20 The young man saith unto him, All these things have I kept from my youth up: what lack I yet?
21 Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the cpoor, and thou shalt have treasure in heaven: and come and follow me.
22 But when the young man heard that saying, he went away sorrowful: for he had great possessions.
I am a little confused about your question. I was referring to the LDS statement that it is works that provides salvation.
Isaiah clearly says that our works are not sufficient and it is only through our relying on the Lord that we are saved. "Good people" will not make it to heaven, because they are covered in sin. Trying to earn your way to heaven will not help you. It is only through confessing your sins and placing your salvation in the hands of Christ that you will be saved from damnation.
I see you stopped short of Matthew 19:25-26.
"When his disciples heard it, they were exceedingly amazed, saying, 'Who then can be saved?'"
But Jesus looked at them and said to them, "With men this (salvation) is impossible, but with God all things are possible."
The purpose of Jesus' comment to the rich ruler was to prove that point.
