Why don't Jesus followers give away all of their stuff , like Jesus said so ?

Answer 1

You need to read that passage in context. After Jesus tells him to keep the commandments, the young man says, "All of these I have observed. What do I still lack?" Then Jesus tells him "If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me", and the man WENT AWAY SAD. He KNEW something was interfering with HIS relationship with the Lord; that is why he asked "What do I still lack?" The fact that he went away sad, unwilling to remove the roadblock Jesus identified confirms this. While we all need to remove our roadblocks, they are not the same for everyone. Joseph of Arimathea was both a rich man AND a disciple of Jesus (Matthew 27:57), because his wealth did not interfere with his following the Lord.

Answer 2

Jesus said that to one man, the rich young ruler. He said it to him specifically because Jesus knew that the man's possessions were a stronghold in his life.

Luke 12:34
"For where your treasure is, there will your heart be also."

Jesus wants all of our heart, not just what is left over after the things that are idols.

Answer 3

The story you refer to concerns believers caring for other believers. This does, in fact, happen today. The primary mechanism to effect this action is the local church. Money is taken for many activities, including a benevolent collection. Through this, other believers - some non-believers, too - are cared for. Often, Christian families will bring food for one another, especially during times of adversity. People volunteer to assist the needy in the congregation all the time.
