For someone with a broadly liberal outlook, it is disconcerting to be called narrow-minded. Before I became a Christian, I saw nothing wrong with sex before marriage, homosexual practice, abortion or inter-faith marriage. Since I accepted that jesus died for my sins, I have struggled with how I should view them. But in the end I accept that God has put forward a particular template for life; who am I as a lowly human to question God? Every time I try to reconcile his law with an opposing world view, I am saying that the manufacturer of the world is wrong. Thats like saying Microsoft cannot know how Word works (probably not the best analogy).
On the contrary, being a Christian has meant that I must be even more open-minded. As Peter writes in Acts chapter 10, God does not show favouritism to one group of people. Jesus died for the sins of all people. He will accept anyone who accepts this truth because they have been cleansed. So, being part of a global church family, i am called to love people whom my liberal self would have seen as the tools of the devil. I am called to love those who live what the bible calls sinful lifestyles because I am a sinner; they need Jesus as much I need him. I am called to love my neighbour because we are all made in God’s image. And finally I am called to love an infinite, eternal, all-powerful, all-knowing God; how can such a God be contained within the limits of mind? I have to open my mind just to consider him.
In truth, it is atheists who are closeminded because they cannot conceive what they cannot see. It is liberals who are closeminded because anyone who disagrees with them is biased, prejudiced, even if the reason for their bias is beyond the limits of this world. (Those who are biased because they hate others who are not like them are just as closeminded.) And finally, those who believe that there is more than one way to God and that all religions are the same are closeminded for not accepting a faith that says there is only one way to God.
In my experience, trying to keep God out involves erecting some kind of mental boundary. It is like living in a closed society, that cannot look over the walls and becoming more and more fearful of what is beyond. The irony is that Jesus is outside, knocking, waiting for you to call him in; at the same time, all God needs is a crack in the wall and he will gradually knock it down.
For the record, I am still a liberal who believes in freedom. That is because only God can really free or liberate the mind.
