Write about someone who always wants more – whether it be money, power, etc. etc.
He said to them, Watch out! Be on your guard against all kinds of greed; a man's life does not consist in the abundance of his possessions. (Luke 12:15) All that you have you cannot take with you. Mortal existence is but a passing venture, a game of chance. All endeth the same. Ashes to ashes. Dust until the soil of the lands. No wealth will save a soul or hinder the passing of time. Nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. (1 Corinthians 6:10) All are born to die.
