Humans and Our Mindset

Now I know that people are a product of their experiences. I've met people this season and their opinions about things i know about really shows that our mindset affects our perception and approach to lifes' circumstances. So trying to make everybody see things the way you see them is very difficult.
The things is even in the churh of God people still see thungs defferently because of their individual backgrounds and cultures. How can the church be united if She if full of people that think differently? The solution is in the Bible. It says in Rom 12:2  Don't change yourselves to be like the people of this world, but let God change you inside with a new way of thinking. Then you will be able to understand and accept what God wants for you. You will be able to know what is good and pleasing to him and what is perfect. Of course we grew up in the world so we are already like the world, our mind works in the way the world has programed it to be overtime so th eresponsibility is for us to change our way of thinking by accepting God's word. The king james says that we should be transfomed by the renewing of our minds. that means that we have to erase our former thinking patterns and align it with what God's word says, I think that once a person can achieve this, Spirituality becomes very enjoyable.  I believe that this cannot happen at once, it takes a continuous process, but God's grace is always available.
