Matthew 6:25-34 “Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes?

Can any one of you by worrying add a single hour to your life? ..
Galatians 3:11 Clearly no one who relies on the law is justified before God, because “the righteous will live by faith.” The law is not based on faith; on the contrary, it says, “The person who does these things will live by them.”
