The Rich Young Ruler we can assume had it all, but he lacked eternal life. He recognised that Jesus could tell him how he could inherit it, and approached him. Jesus, loves the man, and loves him so much that he says he must give away that which is between us, and follow me. The young man, not able to give up his wealth, walks away sad. Jesus wants to be first in our lives, and calls us to put aside or de-prioritise anything that prevents that from happening.
