John Wesley on Matthew 19:21

If thou desirest to be perfect - That is, to be a real Christian: Sell what thou hast - He who reads the heart saw his bosom sin was love of the world; and knew he could not be saved from this, but by literally renouncing it. To him therefore he gave this particular direction, which he never designed for a general rule. For him that was necessary to salvation: to us it is not. To sell all was an absolute duty to him; to many of us it would be ali absolute sin. The young man went away - Not being willing to have salvation at so high a price.
