Must A Rich Man Give All He Has If He Wants To Follow Christ?

Hi guys, I am still curious about what Christ told the young rich man about selling all he has and giving to the poor in Matthew 19:16-30, Mark 10:17-31, and Luke 18:18-30?

I brought this up because some Churches always bring these bible passages up, while others say Christ is not poor so Christians are not supposed to be poor.
