To help you renew your mind you can download and print these helpful tools. Start with the Serenity Prayer to understand the concept. Look at the REBT Godly Beliefs as a model of how to use REBT. Use the blank REBT Worksheet to add your life beliefs and replace them with Godly Truth. 

 Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is - His good, pleasing and perfect will. 

(Romans 12:2)
