Dear
james bond what you appear to be missing is that it isn't necessary to push this justification of faith onto atheists, nontheists or anyone. Because it's faith based anyway. No amount of arguing from this approach is going to change or help anything; in fact it makes it worse by causing more defensiveness back and forth.
As westwall summarized best, existence or nonexistence of God can neither be proven nor disproven but remains faith based. As soon as we can respect that, we can work with our differences without any need to attack, defend or justify why we do or do not follow what someone else believes. There is no need to demonize conflicts and differences because our perceptions are going to remain relative and individual anyway. That doesn't negate one universal truth, just because we all paint and express it differently which is natural given uniqueness of each individual.
What I do believe we can demonstrate by scientific research studies and sociological stats
james bond:
We CAN prove that the spiritual healing and reconciliation process works, based on forgiveness of these differences, in order that we reach CONSENSUS on the MEANING of God Jesus and the Bible.
We can demonstrate by replicated trials and documented experiences that we can reach consensus on meaning WITHOUT having to CHANGE anyone's core beliefs. The nontheist can remain used to using science and secular terms/laws to express what is going on with the world, society and humanity while the theist uses religious symbols for the same.
We can still agree on points, principles, laws and concepts that are universal underneath our diverse ways of seeing and saying these things.
the key that we CAN PROVE is the FORGIVENESS is the factor that makes a difference if we succeed or fail in reconciling and communicating to reach agreement DESPITE our cultural religious political or personal differences.
We can show this by STATS, by documenting the degree of rejection/unforgiveness between people of conflicting groups/beliefs CORRELATING with the rates of success/failure in reconciling conflicts and resolving relationship issues in working together or not toward common goals/solutions.
VS.
the degree and rates of FORGIVENESS/INCLUSION correlating with ability to reach AGREEMENT and work on common solutions across political or religious groups.
