The Pharisees, who loved money,
heard all these things and sneered at him.
And he said to them,
"You justify yourselves in the sight of others,
but God knows your hearts;
for what is of human esteem is an abomination in the sight of God."
Jesus happened to have been the richest person alive at this time. Not in the way we look upon riches, but in heavenly riches. He put all his stock in one source, the source of life who is God.
Jesus was also very poor in the eyes of the Pharisees, because he lacked what the Pharisees love the most which is money.
According to Jesus money is used to justify ourselves in the sight of others. How true! When we have money we have human esteem. People are judged by their financial worth among their peers. Not so much for their accomplishments, but in how they managed to rack up a fortune.
Yet we are told this is an abomination in the eyes of God, why? Is it because we have put more importance on mammon than on God. Yes! Is there any person in this world that does not worry about when they will receive their money. After all we need it to purchase everything that we control in peoples lives. We have then become slaves to mammon, where we would do just about anything to have it. We have become a people that worship mammon, not God.
It's no wonder he sits up there shaking his head at us. What Jesus speaks of and teaches us has never been learned it seems. Because we say we love and worship God, but in the next breath we put all out trust in mammon to get us what we need.
