¹⁵Brothers, let me put this in human terms. Even a human covenant, once it is ratified, cannot be canceled or amended. ¹⁶The promises were spoken to Abraham and to his seed. The Scripture does not say, “and to seeds,” meaning many, but “and to your seed,” meaning One, who is Christ. ¹⁷What I mean is this: The law that came 430 years later does not revoke the covenant previously established by God, so as to nullify the promise. ¹⁸For if the inheritance depends on the law, then it no longer depends on a promise; but God freely granted it to Abraham through a promise. ¹⁹Why then was the law given? It was added because of transgressions, until the arrival of the seed to whom the promise referred. It was administered through angels by a mediator. ²⁰A mediator is unnecessary, however, for only one party; but God is one. ²¹Is the law, then, opposed to the promises of God? Certainly not! For if a law had been given that could impart life, then righteousness would certainly have come from the law. ²²But the Scripture pronounces all things confined by sin, so that by faith in Jesus Christ the promise might be given to those who believe. ²³Before this faith came, we were held in custody under the law, locked up until faith should be revealed. ²⁴So the law became our guardian to lead us to Christ, that we might be justified by faith. ²⁵Now that faith has come, we are no longer under a guardian.
