'Promises' in the Bible

(Now the promises were given to Abraham and to his seed. God did not say 'and to seeds,' as if speaking of many, but 'and to your seed,' since He spoke of only one--and this is Christ.)

God, however, is only one. Is the Law then opposed to the promises of God? No, indeed; for if a Law had been given which could have conferred Life, righteousness would certainly have come by the Law.
