The flood teaches us that human immorality can corrupt all of Creation; Noah teaches us that a single individual can realign Creation with its purpose. Righteous individuals who perfect and live with a balance of these two qualities act as eternal bridges to the Divine. G-d’s pact with Noah will never be broken; in the merit of one man, no flood like that will ever return.
Your actions can uplift the world or destroy it — that is your Divine potential.
