Jesus Teachings
It is ironic that those who preach salvation by grace alone typically cite the apostle Pauls writings but ignore the teachings of Christ himself. While the Book of Mormon teaching that we are saved by grace after all we can do26 may conflict with the theology of some modern Christian groups, it is consistent with Jesus teachings in the New Testament.
The Savior spent three years teaching people the principles by which they should live their lives, never once mentioning grace. His principal message was Repent: for the kingdom of heaven is at hand,27 (which was the same message taught by John the Baptist.28 He upbraided certain cities and said they were under condemnation because they did not choose to repent.29
Christ taught that it was necessary to keep the commandments, both in reality and in thought, in order to enter the kingdom of heaven.30 When the rich young man came to Jesus asking how he could gain eternal life, Jesus began by telling him to keep the ten commandments, then added that he should give his wealth to the poor and follow him.31 He required his disciples to follow his teachings and commandments32 and said that they would be rejected at the judgment day if they did not do so.33 He declared that not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven,34 suggesting that confession of his name, while necessary, is insufficient for salvation.
Jesus also commanded that baptism be performed35 and was himself baptized.36 He told Nicodemus that except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.37 He taught that those who were baptized were considered justified, while those who chose not to be baptized were not justified and were under condemnation.38Prior to ascending to his Father, he instructed the apostles to go to all the world, baptizing in his name and teaching their converts to keep all of his commandments.39 According to Mark 16:16, he declared that he that believeth and is baptized shall be saved.

Of course He did!
It WAS that way until His death and resurrection.
Have you read in Jerimiah that there was to be a NEW covenant [Jeremiah 31:31-34] coming? (And it wasn't the things you swear to during your temple rites; either)
Jesus gave the direct answer to what the requirements were.
He added nothing earlier or later.
Have some Scripture (found in your quad):
Micah 6:8He has shown you, O mortal, what is good. And what does the LORD require of you?
To act justly and to love mercy and to walk humbly with your God.
John 6:28-29
Then they asked him, "What must we do to do the works God requires?Jesus answered, "The work of God is this: to believe in the one he has sent."
1 John 3:21-23
Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything we ask, because we keep his commands and do what pleases him.
And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us.
Here is a simple test for anyone to try; in the manner of Mormon missionaries; praying about the Book of Mormon to see if it is true after reading it: Use this SAME test for other Mormon scripture.
It seems so simple to try. One could do it in the privacy of their own home.
