"And do not be conformed to this world but be transformed By the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God" - Romans 12:2
'That good and acceptable and perfect will' is that the glory of God is displayed through you and that's why you have been empowered with the mind of Christ. The way to prove this to the world is by renewing our minds - doing away with the old way of thinking and having a new way of thinking in Christ, doing away with our old ideas about life and ourselves and getting in God's truths about life and ourselves. God's word is filled with God's truth, what better way to renew our minds than by reading it and letting the truth sink in deep.
Keep at it, keep reading it, keep studying. Be diligent about it. It might just take time but hold on, your mind would change.
