In the parable of the rich young ruler, Jesus had been talking and teaching a great multitude of people, and some young children were brought to him, so that he could pray for them, and the disciples rebuked the people, and Jesus was very displeased with his disciples.
Matt.19:14 - But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven.
Mark10:14-16 - But when Jesus saw [it] he was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God. (15) Verily I (Jesus) say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter there in. (16) And he (Jesus) took them up in his arms, put [his] hands upon them , and blessed them.
Matt.18:3-4 - And said, Verily I (Jesus) say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. (4) Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.
In order to enter the kingdom of heaven, or God, we must become like little children before (or, to) God, eg., as little children, we receive correction and guidance from our parents - so it is with God we will receive correction, guidance and even punishment, because God is not going to allow anybody into the kingdom of heaven who is not true to him. He does not want anybody who may pollute or defile his kingdom. See - What Defiles a Person and Not Everybody Shall Enter the Kingdom of Heaven. Now that I have explained how you can enter the kingdom of heaven or God, I will continue with the rich young ruler.
Matt.19:16-17 - And, behold, one come and said unto him, Good Master, what good thing shall I do, that I may have eternal life: (17) And he (Jesus) 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.
Rev.22:14 - Blessed [are] they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. See - Fruit--Tree of Life
the gate(s) -
Matt.7:13:14 - Enter ye in at the strait gate: for wide [is] the gate, and broad [is] the way, that leadeth to distruction, and many there be which go in thereat: (14) Because strait [is] the gate, and narrow [is] the way, which leadeth unto life, and few there be that find it.
the city - is the holy city or the great city, the holy Jerusalem, descending out of heaven from God. See - The Husband and The Bride--The Kingdom of God
Matt.19:18-19 - He (the one who came and spoke with Jesus) saith unto him (Jesus) Which? (commandments) 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 thy self. See The Great Commandment(s) and Ten Commandments.
Matt.19:20-22 - 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 (wealth).
So Jesus tells us even though we keep the commandments, if we wish to be perfect, we must sell all that we have and give it to the poor and follow him (Jesus) and teach.
Matt.19:23-24 - 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 (Jesus) 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.
So the more wealth that you have and do not share it with the poor, the less likely it is that you will enter the kingdom of God or heaven. See - Mammon or Faith Notice that in verse 23, Jesus said, the kingdom of heaven, while in verse 24, he said the kingdom of God, - they are the same thing. See - The Husband and The Bride--The Kingdom of God
Matt.19:25-26 - When his disciples heard [it], they were exceedingly amazed, saying, Who then can be saved? (26) But Jesus beheld [them], and said unto them With men this is impossible; but with God all things are possible.
To define "all things are possible," let us look at the scriptures in Gen.18, when the Lord appeared unto Abraham. You can read Gen.18:1-8 for yourself, I will begin with verse 9.
Gen.18:9-11 - And they (the three men which appeared to Abraham) said unto him (Abraham) Where [is] Sarah thy wife? And he (Abraham) said, Behold, in the tent. (10) And he (the Lord) said I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard [it] in the tent door, which [was] behind him. (11) Now Abraham and Sarah [were] old [and] well stricken in age; [and] it ceased to be with Sarah after the manner of women.
That is Sarah was now too old to be able to have children.
Gen.18:12 - Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?
Notice that Sarah referred to her husband as lord, but it is written with a small "l" and not with a capital "L" as in God.
I Peter 3:6 - Even as Sara (Sarah) obeyed Abraham, calling him lord: whose daughters (children) ye are, as long as ye do well, and are not afraid with any amazement.
Gen.18:13-15 - And the LORD said unto Abraham, Wherefore did Sarah laugh, saying Shall I of a surety bear a child, which am old? (14) Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son. (15) Then Sarah denied, saying, I laughed not; for she was afraid. And he (the Lord) said, Nay; but thou didst laugh.
Gen.21:1-2 - And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken. (2) For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.
So you see with God, all things are possible, even though Sarah was too old at that time to have children, God intervened to fulfill this prophecy.
Now back to -
Matt.19:27-28 - Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore? (28) And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.
regeneration: - renewing
Titus 3:4-7 - But after that the kindness and love (pity) of God our Saviour toward man appeared, (Jesus), (5) Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing regeneration, and renewing of the Holy Ghost: (6) Which he (God) shed on us abundantly (richly) through Jesus Christ our Saviour; (7) That being justified by his grace, we should be made heirs according to the hope of eternal life. See - Christ, Our High Priest--After the Order of Melchisedec/Melchizedek
and ye also shall sit upon twelve thrones judging the twelve tribes of Israel - this is referring to the twelve disciples
I will quote you one verse from Revelation, chapter 4, and ask that you read the rest of the chapter for youself, as this document is going to be quite long.
Rev.4:4 - And round about the throne [were] four and twenty seats (24 seats): and upon the seats I (John) saw four and twenty elders sitting, clothed in white raiment; and they had on their heads crowns of gold.
So there will be the twelve disciples, as well as twelve others who were men of God, eg. Abraham, Moses, Noah, Isaac, Elizah, Daniel, Job, Jacob, John the Baptist - these are some of the men who could be among the other twelve, I am not saying these are definitely them.
Matt.19:29 - And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive an hundredfold, and shall inherit everlasting life. (30) But many [that are] first shall be last; and the last [shall be] first.
Matt.20:16 - So the last shall be first, and the first last: for many be called, but few chosen.
Let us look at the version in the book of Mark
Mark 10:28-31 - Then Peter began to say unto him (Jesus), Lo, we have left all, and have followed thee. (29) And Jesus answered and said, Verily I say unto you, There is no man that hath left house, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my sake, and the gospel's, (30) But he shall receive an hundredfold now in this time, houses, and brethren, and sisters, and mothers, and children, and lands, with persecutions; and in the world to come eternal life. (31) But many [that are] first shall be last; and the last first. See - Workers in the Vineyard
The closer it gets to the return of Jesus - the less amount of time people are able to serve the Lord, and Jesus will start with the last ones who come to serve him, that is, those who keep the commandments of God and work to spread the word of the Lord, forsake all (everything), to inherit life everlasting, or eternal life.
So even though the rich young ruler kept all the commandments, he was not willing to give up all his wealth and follow Jesus, and this is what Jesus told him to do if he wished to be perfect and have eternal life.What Defiles a Person
