Trust-faith is always a personal affair, a decision made by individuals based on particular reasons that make a convincing case to the decider. Such is conviction. Assurance is a strong confidence that our conviction and trust is well-founded, having weighed the evidence from different perspectives, including the possibility that we may just be wrong in our conclusion, but that that is quite unlikely. Hope is what flows from this combination for hope looks to the future with new eyes, new understanding, new possibilities and vistas founded on trust-faith, and the conviction and assurance that ground it and give it depth.
Theists, atheists, agnostics, polytheists, Deists, monists, pantheists – it matters not. We are bred to believe, not just to exist. We are made and formed to trust that there is meaning behind the blind-seeming, ineluctable powers and forces enveloping us in the time-space continuum, or the quantum-chance continuum if you prefer.
