I know for certain that God exists but I am Libertarian who by definition does not surrender to man or God.
For me exposing truth is the highest religion. I have always done that. I do it through the process of satya-advaita yoga. It is a scientific method of being at one with truth or truth-accommodation. This is to say to seek the truth, to expose the truth and never let truth get covered up. This method has led me to the knowledge of being certain that God exists as a Personal God.
