This young ruler showed great earnestness. He asked what he should do now, that he might be happy for ever. Most ask for good to be had in this world; any good, Ps 4:6; he asks for good to be done in this world, in order to enjoy the greatest good in the other world.
Christ encouraged this address by assisting his faith, and by directing his practice. But here is a sorrowful parting between Jesus and this young man. He asks Christ what he shall do more than he has done, to obtain eternal life; and Christ puts it to him, whether he has indeed that firm belief of, and that high value for eternal life which he seems to have.
Is he willing to bear a present cross, in expectation of future crown? The young man was sorry he could not be a follower of Christ upon easier terms; that he could not lay hold on eternal life, and keep hold of his worldly possessions too.
He went away grieved. See Mt 6:24, Ye cannot serve God and mammon.
