Galatians, Lesson 9: The Relation of the Law to the Promise

Galatians 3:15-22

INTODUCTION: The foregoing argument (3: 1-14) introduced the Abrahamic promise of justification by faith and showed that it could not be received by keeping the law of Moses. Paul, it seems, anticipates two questions from this discussion. First, since the law was from God did it not in some way relate to the promise? Second, what was the purpose of the law if only to be abolished at the cross? Paul answers with a two fold argument.
I. PRIORITY OF THE PROMISE OVER THE LAW, 3: 15-18.
A. Two facts considered in 15-16.
1. Two characteristics of confirmed covenants (in Paul's time)) 15. Confirmed covenants (1) could not be annulled (2) could not have conditions later added to them as necessary in order to inherit.
2. The promise(s) were to Abraham and to Christ his seed, 16.
B. Application of facts to the law and promise, 17-18. Notice Paul's “Now this I say,” which introduces his application of the facts to the subject.

1. The promise was made and confirmed four hundred and thirty years before the law of Moses was given. Therefore according to the law concerning confirmed covenants the law of Moses could neither nullify the promise as given, nor could the law be added to the promise as a condition necessary to inherit the promised blessing.


2. We are to receive the blessing of justification exactly as God promised it. God promised that the blessing was to come through Christ by faith (Gal. 3:8, 16). It was not promised to come any other way. Therefore if we inherit the promised blessing by the law rather than through faith as promised, then justification would not come as God promised it would – by faith in Abraham's seed. But God granted the promise (of justification) to Abraham through his seed and God would fulfill it that way.

II. THE PURPOSE AND NATURE OF THE LAW, 3: 19:22.
A. To make one consciousness of sin, 19a. To make men realize they are sinners, (cf. Rom. 3:20; 7: 9-13) and bring them to a need for Christ and salvation.
B. The nature of the law, 19b-22.
1. Temporal, 19b. “Till the seed should come.” Then was done away in Christ at the cross (Cf. 2 Cor. 3:14; Eph: 2:15).
2. Inferior to the covenant of Promise, 19c-20. The law was given mediately: God- angels – Moses – Israel (Cf. Acts 7:53; Heb.2:2). The promise was given to Abraham immediately: God – Abraham. Even as Jesus came to us to give us the new covenant. Cf. Heb. 23. Hence, no mediator between God and Abraham as between God and Israel.


3. Unable to hinder the promises, 21-22. In the promise was to come through the law of Moses it would hinder the promised blessing of justification by faith, for the law condemned the lawbreaker. How then could it possibly justify?! Cf. Acts 13:38-39. But since the promise was given by faith the law cannot hinder sinners (lawbreakers) from being justified, inasmuch as we can be justified (reckoned as righteous) through Christ's sacrifice.
CONCLUSION: All are under sin! The law says so. But all can be justified! Christ and the resurrection say so. It's just a matter of believing.
