The Bible speaks of being transformed by the renewing of your mind in the book of Romans. To attract the right relationship and the love you have in your heart, it is important to counter negative thoughts with positive affirmations.
For example, if you believe the people you attract will eventually cheat and break your heart, then you will have that experience in love until you make a conscious decision to renew your mind. No matter what has happened to you previously, you can break the barriers to love.
I encourage you to use these proclamations as daily reminders of who you are in Christ, the love He wants you to experience and the love He has for you.
