²⁰ Now a go-between (intermediary) has to do with and implies more than one party [there can be no mediator with just one person]. Yet God is [only] one Person [and He was the sole party in giving that promise to Abraham. But the Law was a contract between two, God and Israel; its validity was dependent on both].

²¹ Is the Law then contrary and opposed to the promises of God? Of course not! For if a Law had been given which could confer [spiritual] life, then righteousness and right standing with God would certainly have come by Law.

²² But the Scriptures [picture all mankind as sinners] shut up and imprisoned by sin, so that [the inheritance, blessing] which was promised through faith in Jesus Christ (the Messiah) might be given (released, delivered, and committed) to [all] those who believe [who adhere to and trust in and rely on Him].
