“Blessed are You, Hashem, our G-d, King of the universe, Who formed man with wisdom and created within him many openings and many hollows (cavities). It is obvious and known before Your Throne of Glory that if but one of them were to be ruptured or if one of them were to be blocked it would be impossible to survive and to stand before You (even for a short period of time). Blessed are You, Hashem, Who heals all flesh and acts wonderously.”
Come to find out (thanks, Sarah!) that the Asher Yatzar is a Jewish blessing, found in the Talmud, that was written approximately 1600 year ago by a 4th century rabbi named Abayei.*
I thank God for a body that works properly; one which He has provided with ways to eliminate death and decay.
And how much more do I thank Him for the way He provided, through Jesus Christ, to eliminate the death and decay that seeks to claim my soul!
