How you respond can have the power to change things. Whether its responding with prayer and fasting, or responding with grace and kindness when you have the right to do the opposite, or with patience - how you respond can change the outcome of a thing. Whether you run to God or to a carnal choice it will show. Even if our response does not change the person or situation, it can shift you and how you react. How do you approach things when they come to you?
