While i do understand where you are coming from, Biblically being "religious" is not about some abstract faith which does not result in reality, but faith in the God of Abraham, Isaac and Jacob who knew God to be a realiy and saw Him act consistent with His promises (and thus no one can ignore the Jews today). The miracles God did in delivering the Hebrews from Egypt revealed to other nations who the true and living God was. And while, as i conceded, simple intellectual arguments may not persuade the heart, the observable effects which correspond to the claims of God help others to take the step of faith by which they may know God is real, when His promised Holy Spirit (Joel 2) comes in as a result of their honest faith in the promised Messiah (Is. 7:14; 53; Micah 5:2). And this Jesus i know, even today, to be very real. Praise the Lord.
