Religion must be based on both faith and reality. Of course, there will be an element of faith present.
However, any religion that strays too far from reality will be easily disproven.
Therefore, the best religion will be that which most closely aligns with reality, fact, and truth.
However, the truth of religion will primarily be the type of truth one searches for in history and archeology. I cannot prove to you, for example, that Lincoln is actually the mind that gave rise to the Gettysburg Address. He could have simply written as someone whispered words in his ear.
However, it is his handwriting. Is that 100% proof? Nope. But, it is logically true within a reasonable doubt.
Thank you so much for sharing your insights, dear brother in Christ!
Christianity is easily disproven. All of its prophecies have failed to materialize. Christianity doesn't have a single accurate verifiable prophecy that has been fulfilled. Christianity is falsified.
But like AGW alarmists, the falsification of their models makes them even more strident. Cognitive dissonance hurts. Cognitive dissonance is also why the Moslems hate the west.
