One of the greatest “love blockers” in our lives is the lack of believing that someone actually loves you. Insecurity can cause you to start backing away in a manipulative way. Insecurity causes us to jump to conclusions. Insecurity can cause you to be controlling. Insecurity can cause you to be cutting. Insecurity is self-fulfilled prophecy of broken relationships. God and others are only able to love me as much as I believe they love me.
