Religion has always been a contentious issue. The Bible records several incidents of conflict arising from peoples choice in what they wish to believe. Even today the fight continues, Christians war against Muslims while practices that have long been condemned are now recognized. Perhaps what is most interesting is how many of us accept a religious practice without looking into its history. In the Caribbean for example, people attend churches where at one time their fore parents were human vehicles that transported their masters and had to wait far away from the building while their masters prayed to God.
Millions of people all around the world sing "Amazing Grace" without any knowledge of its history. A song that was conceived on a slave ship. Muslims sometimes kill their brothers and sisters in the name of religion.Others rather an animals survive than feeding starving people with its meat. In all these practices followers are though not to question but accept by faith.
Faith, however, simply means believe without proof.
