An idol will ALWAYS break your heart.
Bad priorities will destroy you (putting something over God). Just watch.
Solution: Apply the Gospel to your idol. So: A spouse is just a spouse; a career is just a career.
Not addressing the idol + applying the Gospel is not as effective as addressing the idol + applying the Gospel. Take out the bad and put in the good. Paul always addressed the idols wherever he went.
Simply saying that “I will try hard to change” will not help you get rid of a bad habit and to change, but instead, you must have an overpowering, positive affection driving that change. That needs to be God.
