'Promises' in the Bible

Now the promises [in the covenants] were decreed to Abraham and to his seed. God does not say, “And to seeds (descendants, heirs),” as if [referring] to many [persons], but as to one, “And to your Seed,” who is [none other than] Christ.

Is the Law then contrary to the promises of God? Certainly not! For if a system of law had been given which could impart life, then righteousness (right standing with God) would actually have been based on law.
