Gain the Whole World, and Lose His Own Soul
The teaching of Christ Jesus where His thoughts were clearly expressed is as follows:
34 And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me.
35 For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel's, the same shall save it.
36 For what shall it profit a man, if he shall gain the whole world, and lose his own soul?
37 Or what shall a man give in exchange for his soul?
38 Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels. (Mark 8)
The core of these words is "what shall a man give in exchange for his soul?" Indeed, today everybody sells some parts of his/her soul to Satan so as to get any money and accumulate material wealth. This is the decisive source and cause for problems in the human world.
But desire for material happiness is so strong that everybody naturally wants to get it even by selling its soul to Satan. Conversely Satan makes everybody wants material happiness or life of billionaire so as to sell any part of its soul to Satan who teaches it how to use crafts or tricks to get profits. And Satan teaches people to forget teachings of the God and neglect poor neighbors so as to get money and accumulate wealth. On this Satan's teaching, lives of most people are built.
So, Christ Jesus taught people to abandon this world and material happiness but to keep one's soul. And then, one will be accepted in Heaven after its death in this world.
So, it is whether you take happiness in Heaven after death in this world or material happiness in this world. If one takes the latter, he shall be rejected in Heaven so as to go to and live in the hells to be ruled by Satan.
In other word, it is whether or not you believe in the afterlife or the spirit world where Heaven and the hells exist. But human science has not yet assured that there is the afterlife or the spirit world. And, human science has not revealed the conditions for being accepted in Heaven if the afterlife and Heaven existed. Rather, it seems that Satan teaches people that one's being rich in this world will not prevent it from being also happy in the afterlife. So, Satan tells people that they can be materially happy in this world and also in the afterlife, so that they should sell any part of their souls to Satan to be materially happy in this world while living in this world. And, this Satan's teaching seems to be accepted by most of people, so that everybody is seeking money even by selling their souls to Satan.
So, if you are brainwashed by Satan, you will still seek money and continue to accumulate wealth if you find that there is the afterlife of the spirit world.
Yet, Christ Jesus taught that if we got even this world by selling our souls to Satan, we would be rejected by Heaven. Indeed, those who sold their souls to Satan cannot be accepted in Heaven.
So, if one knows that there is the afterlife, it is useless unless he accepts the teaching of Christ Jesus about the conditions for being accepted in Heaven. But, this truth cannot be scientifically proved. Indeed, faith is to believe something that science cannot prove.
Yet, although science cannot prove whether the words of Christ Jesus are correct, men can judge and accept them instinctively. Those who love evil will accept Satan's teaching but others who love good will accept the teaching of Christ Jesus. And, scientifically it cannot be judged whether Satan's teaching is correct or the teaching of Christ Jesus is. It depends on whether one loves evil or good, or specifically Satan or the God, or otherwise hatred, madness, and wealth or love, rationale, and poverty.
Through poverty in this world realized by our rejecting to sell our souls to Satan, we can see truth since we keep our souls. And following the truth and love, we can reach Heaven.
But how can we live without money in this world? So, it is faith to believe that the God will save and help us if we do not have money in this world. And, understanding that there are the afterlife, Heaven, and the hells should support this faith. But, we have to also understand other teaching of Christ Jesus that rich men cannot be accepted in Heave. So, what a great blessing to poor people the teaching of Christ Jesus is!
Mark 10, King James Version
3 And he answered and said unto them, What did Moses command you?
4 And they said, Moses suffered to write a bill of divorcement, and to put her away.
5 And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept.
6 But from the beginning of the creation God made them male and female.
7 For this cause shall a man leave his father and mother, and cleave to his wife;
8 And they twain shall be one flesh: so then they are no more twain, but one flesh.
9 What therefore God hath joined together, let not man put asunder.
