Romans 12:2 tells us to not be conformed to this world but to be transformed by the renewing of your mind. When we read and meditate on His Word it renews our minds, allowing us to put God and the things of God above and ahead of all other things. We believers are growing spiritually and are to be focusing on Godly values and beliefs, on what would be pleasing to Him. Having His Word displayed in front of our eyes renews our mind and our perspective.
