Charles Spurgeon Commentary Mark 10:21

"And Jesus looking upon him loved him, and said unto him, One thing thou lackest: go, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, follow me." — Mark 10:21 (ASV)

Then Jesus beholding him loved him,

There was so much that was amiable about him.

And said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me.

He knew that there was a weak point in the young man's character—that he did not yet supremely love God, but loved his wealth—that he was living for this world, after all. And are there not many such—most correct in character? No one could point to a single flaw in their morals, but they are living purely for self—altogether that they may buy and sell, and get gain. No thought of God, except a fear lest they should come under his rod, but no thought of serving him, and laying themselves out for his glory, nor much thought, either, for their fellow men. Christ had hit the blot—marked it out for him.
