Affirmation: It’s the repetition of affirmations that leads to belief. And once that belief becomes a deep conviction, things begin to happen. — Muhammad Ali [born Cassius Marcellus Clay Jr. (1942–2016) American boxer and activist

Truth and Conviction
The sincere conviction that something is true will allow the individual who holds that conviction to resonate with a power that presents an argument for truth. Yet that person could be wrong. As a matter of fact, the only thing that may be right is the sincerity of the conviction. Therefore the individual should do whatever he or she can to make their belief resonate with truth.
     For example, a vessel much larger than described would be needed for Noah to carry two of every species on the planet; but those who believe this “fact” sincerely, do whatever they can to make it true. They try to make it consistent with logic. If it could be proved or disproved by some objective means, then they could rejoice in their accurate belief or would have to readjust their conviction.
     Actual facts as well as facts of belief have the resonance of truth when spoken with conviction. The listener must decide what is objective truth, subjectively true, or, more likely, a combination of both – and how to segregate them.
     Actual truth is always scientifically provable, intellectually logical, and spiritually virtuous.
