“Does God exist?” A question that many people have argued about for a long time.
Personally I think that belief or faith in the existence of God is a personal choice. We should all respect that different people will make different choices. We should not get upset or argue unpleasantly with people over that choice it is their own to make. Faith, after all, is a matter of believing in something for which there is no immediate evidence. Hence, it must be a choice for us all to make, and I do not mind what choice you make, that is between you and God.
What matters, is the impact that that choice make on your life. Does your choice to believe, or not, in the existence of God, develop your character in such a way that your life has a positive or negative impact on the lives of others. What is the external visible result of that personal internal choice?
