Many of the things experienced in this life have an end. The rich young ruler was surprised and saddened to learn that his riches were fleeting and could not endure in the path toward a fullness of joy:
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 poor, 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.
23 Then said Jesus unto his disciples, Verily I say unto you, That a rich man shall hardly enter into the kingdom of heaven. 24 And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God. (Matthew 19)
There are, however, things that endure forever:
19 Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
20 But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
21 For where your treasure is, there will your heart be also. (Matthew 6)
In one exchange, the Lord made a distinction between what will endure and what is fleeting:
38 Now it came to pass, as they went, that he entered into a certain village: and a certain woman named Martha received him into her house.
39 And she had a sister called Mary, which also sat at Jesus’ feet, and heard his word.
40 But Martha was cumbered about much serving, and came to him, and said, Lord, dost thou not care that my sister hath left me to serve alone? bid her therefore that she help me.
41 And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things:
42 But one thing is needful: and Mary hath chosen that good part, <u>which shall not be taken away from her. (Luke 10)</u>
In a sense, life is about searching for and obtaining the “good part”—the things “which shall not be taken away,” but will endure forever.
God knows what endures and what does not, and his gospel is about providing the path to those things that endure:
10 And if it so be that the church is built upon my gospel then will the Father show forth his own works in it.
11 But if it be not built upon my gospel, and is built upon the works of men, or upon the works of the devil, verily I say unto you they have joy in their works for a season, and by and by the end cometh, and they are hewn down and cast into the fire, from whence there is no return. (3 Nephi 27)
13 And everything that is in the world, whether it be ordained of men, by thrones, or principalities, or powers, or things of name, whatsoever they may be, that are not by me or by my word, saith the Lord, shall be thrown down, and shall not remain after men are dead, neither in nor after the resurrection, saith the Lord your God.
14 For whatsoever things remain are by me; and whatsoever things are not by me shall be shaken and destroyed. (D&C 132)
If we seek and trust in God, we will learn what endures and what does not. We will obtain what endures, and it will never be taken away.
