"So many Christians, but I don't see any of them selling what they have and giving it all to the poor, like Jesus taught!"
The inability to Read With Comprehension is a vanishing skill. With parents both working to keep up with living AND the taxes, and day-care struggling with overcrowding and staying out of the attention of regulators AND the news stations, and schools mandated to teach test-taking abilities and thus avoid the attention of regulators AND the news stations...there is little time to inculcate much beyond passing eyes over text, and defining sounding it out in one's head as "reading". Few places does this show up faster than in conversations with Biblical content. The Rich Young Ruler session that Jesus had is a case in point.
18 And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life?
19 And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God.
20 Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother.
21 And he said, All these have I kept from my youth up.
22 Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me.
23 And when he heard this, he was very sorrowful: for he was very rich. Luke 18:18-23 (KJV)
Yet, while the exchange was between Jesus and the Rich Ruler, we may certainly derive counsel from their talk. Don't let your Stuff come between you and the Kingdom of God. Christ is more important than stocks and shares and real estate, oh my. You are never as good as you think you are. AND, Jesus speaks precisely. He is the Word, the Logos made flesh, Who said "Let there be...", and there was.
He is not going to bobble a noun.
If I go to a naturopath for my cerebral chilblains, and he prescribes a tincture of goldenseal root and kerosene, and it makes me well, that does not give him, or me, or the TV talk host who interviews us, license to prescribe the vile brew to everyone, for anything. So it is with the Rich Ruler interview. Jesus prescribed what HE needed. If I have trouble with gluttony, or lust, the prescription will fit the sin.
Don't make Jesus the Spokesprophet for your political or social druthers. Instead, bow to His Lordship, and take your personally prescribed medicine. Don't walk away grieving. As the Mark account said:
21 Looking at him, Jesus felt a love for him and said to him, “One thing you lack: go and sell all you possess and give to the poor, and you will have treasure in heaven; and come, follow Me.”
Jesus prescribes with love.
