In the Book of Mormon we read that unless a man endures to the end, He cannot be saved. We need to follow the example of Jesus. We need to repent, be baptized, and receive the Holy Ghost. After we have entered the narrow path, we need to continue to have unshaken faith in Christ who is mighty to save. We must press forward with a steadfastness in Christ, feasting upon the word of God and endure to the end. If we do this, we will obtain eternal life. There is no other way to be saved than through the name of Jesus Christ. 2 Nephi 31:16-21 " And now, my beloved brethren, I know by this that unless a man shall endure to the end, in following the example of the Son of the living God, he cannot be saved. Wherefore, do the things which I have told you I have seen that your Lord and your Redeemer should do; for, for this cause have they been shown unto me, that ye might know the gate by which ye should enter. For the gate by which ye should enter is repentance and baptism by water; and then cometh a remission of your sins by fire and by the Holy Ghost. And then are ye in this strait and narrow path which leads to eternal life; yea, ye have entered in by the gate; ye have done according to the commandments of the Father and the Son; and ye have received the Holy Ghost, which witnesses of the Father and the Son, unto the fulfilling of the promise which he hath made, that if ye entered in by the way ye should receive. And now, my beloved brethren, after ye have gotten into this strait and narrow path, I would ask if all is done? Behold, I say unto you, Nay; for ye have not come thus far save it were by the word of Christ with unshaken faith in him, relying wholly upon the merits of him who is mighty to save. Wherefore, ye must press forward with a steadfastness in Christ, having a perfect brightness of hope, and a love of God and of all men. Wherefore, if ye shall press forward, feasting upon the word of Christ, and endure to the end, behold, thus saith the Father: Ye shall have eternal life. And now, behold, my beloved brethren, this is the way; and there is none other way nor name given under heaven whereby man can be saved in the kingdom of God. And now, behold, this is the doctrine of Christ, and the only and true doctrine of the Father, and of the Son, and of the Holy Ghost, which is one God, without end. Amen.
In the Old Testament we read that children of murderers should not be put to death for the sin of their fathers. Each person is held accountable for their own sins. 2 Kings 14:6 "But the children of the murderers he slew not: according unto that which is written in the book of the law of Moses, wherein the Lord commanded, saying, The fathers shall not be put to death for the children, nor the children be put to death for the fathers; but every man shall be put to death for his own sin."
Some scriptures with a thought booklet tell us that when Jesus heard that Lazarus was sick, instead of immediately going to him, he stayed where he was for two days. As a result, Lazarus died. Why did Jesus delay going to is friend and healing him before he died? Jesus could have prevented Lazrus' death. But Jesus wanted to show more than that He could conquer illness. He'd already healed the blind and the lame to demonstrate his power over sickness. Jesus wanted to show the glory of God in demonstrating His power over death. It's wonderful that Jesus heals many illnesses, but ultimately He defeats death--our own death and the death of all our loved ones. We need Him to defeat death for us and give us eternal life. John 11:1-46 "Now a certain man was sick, named Lazarus, of Bethany, the town of Mary and her sister Martha. (It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.) Therefore his sisters sent unto him, saying, Lord, behold, he whom thou lovest is sick. When Jesus heard that, he said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby. Now Jesus loved Martha, and her sister, and Lazarus. When he had heard therefore that he was sick, he abode two days still in the same place where he was. Then after that saith he to his disciples, Let us go into Judæa again. His disciples say unto him, Master, the Jews of late sought to stone thee; and goest thou thither again? Jesus answered, Are there not twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world. But if a man walk in the night, he stumbleth, because there is no light in him. These things said he: and after that he saith unto them, Our friend Lazarus sleepeth; but I go, that I may awake him out of sleep. Then said his disciples, Lord, if he sleep, he shall do well. Howbeit Jesus spake of his death: but they thought that he had spoken of taking of rest in sleep. Then said Jesus unto them plainly, Lazarus is dead. And I am glad for your sakes that I was not there, to the intent ye may believe; nevertheless let us go unto him. Then said Thomas, which is called Didymus, unto his fellow disciples, Let us also go, that we may die with him. Then when Jesus came, he found that he had lain in the grave four days already. Now Bethany was nigh unto Jerusalem, about fifteen furlongs off: And many of the Jews came to Martha and Mary, to comfort them concerning their brother. Then Martha, as soon as she heard that Jesus was coming, went and met him: but Mary sat still in the house. Then said Martha unto Jesus, Lord, if thou hadst been here, my brother had not died. But I know, that even now, whatsoever thou wilt ask of God, God will give it thee. Jesus saith unto her, Thy brother shall rise again. Martha saith unto him, I know that he shall rise again in the resurrection at the last day. Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: And whosoever liveth and believeth in me shall never die. Believest thou this? She saith unto him, Yea, Lord: I believe that thou art the Christ, the Son of God, which should come into the world. And when she had so said, she went her way, and called Mary her sister secretly, saying, The Master is come, and calleth for thee. As soon as she heard that, she arose quickly, and came unto him. Now Jesus was not yet come into the town, but was in that place where Martha met him. The Jews then which were with her in the house, and comforted her, when they saw Mary, that she rose up hastily and went out, followed her, saying, She goeth unto the grave to weep there. Then when Mary was come where Jesus was, and saw him, she fell down at his feet, saying unto him, Lord, if thou hadst been here, my brother had not died. When Jesus therefore saw her weeping, and the Jews also weeping which came with her, he groaned in the spirit, and was troubled, And said, Where have ye laid him? They said unto him, Lord, come and see. Jesus wept. Then said the Jews, Behold how he loved him! And some of them said, Could not this man, which opened the eyes of the blind, have caused that even this man should not have died? Jesus therefore again groaning in himself cometh to the grave. It was a cave, and a stone lay upon it. Jesus said, Take ye away the stone. Martha, the sister of him that was dead, saith unto him, Lord, by this time he stinketh: for he hath been dead four days. Jesus saith unto her, Said I not unto thee, that, if thou wouldest believe, thou shouldest see the glory of God? Then they took away the stone from the place where the dead was laid. And Jesus lifted up his eyes, and said, Father, I thank thee that thou hast heard me. And I knew that thou hearest me always: but because of the people which stand by I said it, that they may believe that thou hast sent me. And when he thus had spoken, he cried with a loud voice, Lazarus, come forth. And he that was dead came forth, bound hand and foot with graveclothes: and his face was bound about with a napkin. Jesus saith unto them, Loose him, and let him go. Then many of the Jews which came to Mary, and had seen the things which Jesus did, believed on him. But some of them went their ways to the Pharisees, and told them what things Jesus had done."
