Depth and Diversity of Evidence
Not all arguments have the same depth. Some may be understood by a simple desert dweller, while others are contemplated by physicists or biologists.
One person may be moved by causality, another by design, and another by scientific or moral indications.
The diversity of arguments is therefore a mercy for different minds and levels of reflection.
How the Arguments Support One Another
These arguments are different faces of one meaning: this universe has an originator, Creator, and wise governor.
The Big Bang supports causality and contingency; fine-tuning supports design; purpose relates to wisdom and planning.
We therefore do not see the arguments as isolated islands, but as one structure whose parts reinforce each other.
