For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”
Deuteronomy 27:26
‘Cursed is he who does not confirm the words of this law by doing them [keeping them, taking them to heart as the rule of his life].’ And all the people shall say, ‘Amen.’
