21 Then Jesus, looking at him, loved him, and said to him, "One thing you lack: Go your way, sell whatever you have and give to the poor, and you will have treasure in heaven; and come, take up the cross, and follow Me." 22 But he was sad at this word, and went away sorrowful, for he had great possessions.
