Does God really exist?

I believe that there is only one true God, and that people just have different ways of calling him, hence different religions. I am a catholic and I believe that my God is real. As much as I would want to convert the people here in believing him, I know it's not right to force people into believing. Here's just my two cents about my God: Religion isn't about doing good just so you'd go to heaven. It's about believing, truly believing that God exists and you giving your life to serve him. We are just mere servants, and we should devote our life in doing good for Him, in pleasing Him.

I think there is one God for all the religions, but everyone had their own views/ways the wanted people to be so they created a religion.

Even if he does not, people around the world still benefit from the idea that God exists. As an example of God's effect to a person, you can read the story by the link: http://refocusingoureyes.com/darkness-light
