What did Christ mean when He promised "treasure in heaven" to the rich ruler in Mark 10?

Mark 10:17 FF provides the narrative of he rich young ruler who came to Jesus with the question of securing eternal life. “And when he was gone forth into the way, there came one running, and kneeled to him, and asked him, Good Master, what shall I do that I may inherit eternal life?”

In answer to that question Christ points him to the Law—“Thou knowest the commandments…”— and beyond—“go thy way, sell whatsoever thou hast, and give to the poor…and come, take up the cross, and follow me.”

In the midst of that directive Christ makes a promise: “thou shalt have treasure in heaven….”

Discussion in other formats generally incline that this is not a salvific promise at all. That it is some sort of promise in response to a question in regards to securing eternal life can hardly be in doubt, however.

What think ye? is it a salvation promise? a merely theoretical premise? or other?

Discussion

1. Well, if the rich man was asking questions regarding how to entet heaven (=eternal life, salvation), Jesus’ answer, we would assume, be be answered accordingly.

2. The “treasure” being sought is “in heaven” so, logically and clearly, the answer has to do primarily with salvation.

It seems to me that how anyone can interpret it in any other way than salvific is really stretching …dontcha think?
