Consider:

2 Timothy 3:16-17 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work

Through theological studies, expanding knowledge on them, and including various religions, can show us this is a common theme in them all. But i admit, the Holy Bible as it is now is key into building the solid foundation that allows you to successfully reach out from there and ponder the truth of matters.
