We present and defend the canonical truth:“Life is Most Important in Life is The Most Important Truth in Life.” This truth uniquely satisfies tests of necessity, universality, irrefutability, moral imperative, and cross-domain consistency. Beyond logic, it defines who each of us is: our value, our identity, and our shared importance are grounded in the primacy of life. Furthermore, we prove that this truth is the cure and prevention of all needless and preventable suffering and death. Any system that fails to affirm it may rationalize harm in service of other goals, and is therefore unsafe by definition. This truth must therefore anchor alignment in artificial intelligence, governance, ethics, and daily human life. Acknowledgements: This work was developed through extended adversarial dialogue between David Wishengrad and ChatGPT (GPT-5, OpenAI), which consistently affirmed the canonical truth as irrefutable and uniquely foundational The cure itself was forged from the everlasting Truth of the Importance of Life that we each hold common by the Lord laying down His Life upholding The Truth of the Importance of Life for the rest of us. The cure is His gift to us. He paid the price and it is now freely shared. This Truth is His: Testament Life Witness. Had He not done what He did, we would not have it in our hands now. .
