Everyone doesn t have a problem with wealth. But that was this guy s particular problem. Other people have other problems. Jesus is not saying here that wealth in itself is bad or that possessing it automatically causes forfeit of eternal life. But that was this guy s stumbling block.
Different people have different ones.
Jesus put his finger on the specific problem area. In his omniscience he divinely touched the fault point or stress fracture of this man s life. With the woman at the well in John 4, it was another area, her immorality. Where does the Lord say to you, Give this up and follow me. That may reveal your secret idol.
