What does the Bible say about worry? Well, the main thing that you should do is to try to NOT worry. Do not worry about tomorrow for tomorrow will worry about itself. This is one of the most powerful scriptures in the Bible and one that you should live by. That verse alone is capable of inspiring an inner peace within a Christian that will prevent so many worries, fears, and even sins.
If you trust in God, then there is no need to worry about your life. One of the best sayings to live by is "let go and let God." The only thing that worryin will do is ruin your day - the emotion will make things dark. However, if you just open yourself up to the light and love of God, then the idea of "worry" is not something that will bother you.
If you read Bible verses about worry, it will help you understand why it isn't an important emotion. That is more important is that you should pray as a Christian and trust in God instead of worrying as a Christian. Don't let your heart be heavy!
