Question 1

What is Paul’s everyday-life comparison in verse 15, and what is it meant to establish?

Accepted Answer

In v.15 Paul appeals to a basic social reality: when a human agreement has been confirmed, people do not later cancel it or add new terms to it. His point is not mainly to teach contract law but to establish a common-sense principle of stability and sequence. He then uses that principle as a frame for the rest of the paragraph: if that is true even for human arrangements, then God’s earlier promise to Abraham should be treated as firmly established and not subject to being rewritten by something that comes later in history (vv.17–18).

Question 2

According to verses 16–17, who received the promises, and how does Paul connect that to Christ?

Accepted Answer

Paul says the promises were spoken to Abraham and to his “seed” (v.16). He highlights that Scripture says “seed” (singular) rather than “seeds” (plural), and then he states his conclusion: that “seed” is Christ. In v.17 he continues the same line of thought by saying the covenant was confirmed beforehand by God “in Christ,” and that the later law cannot annul it. Taken together, Paul links the Abrahamic promise to Christ as its focused endpoint or fulfillment, not merely to Abraham’s descendants in general.

Question 3

What does verse 17 claim about the timing of the law and its effect (or lack of effect) on the promise?

Accepted Answer

Verse 17 states a timeline and a consequence. The timeline is that the law came “four hundred and thirty years” after the earlier covenant was confirmed by God. The consequence is that the later law does not annul that earlier arrangement and therefore cannot make the promise ineffective. Paul’s logic depends on sequence: a later development (the law) cannot cancel what God previously established. The verse is less about reconstructing Israel’s chronology in detail and more about securing a theological conclusion from the premise that the promise is earlier and confirmed by God.

Question 4

In verse 18, what is the “either-or” Paul sets up between law and promise, and what conclusion does he draw?

Accepted Answer

Paul argues that “inheritance” cannot be grounded in the law and still be grounded in promise in the same way. He says that if inheritance is “of the law,” it is no longer “of promise” (v.18). Then he gives his conclusion: God granted it to Abraham through promise. Within this paragraph, “law” represents a basis that would make inheritance depend on later terms, while “promise” represents God’s earlier grant to Abraham. Paul’s main point is about basis and source: inheritance rests on God’s granting promise rather than the later law.

Question 5

What does Paul appear to mean by “inheritance” in this immediate argument, based on verses 16–18?

Accepted Answer

The passage does not define “inheritance” with a full list, but it ties it directly to what God “granted” to Abraham by promise (v.18) and to the promises addressed to Abraham and his “seed” (v.16). In the flow of Galatians 3, Paul is discussing how people are included in Abraham’s blessing and how God’s pledged gift is received, in contrast to making the law the controlling basis. So “inheritance” here is best read as shorthand for the promised share in what God pledged through Abraham—something ultimately connected to Christ, since Paul identifies the “seed” as Christ (v.16).

Question 6

What does Paul’s use of “seed” (singular) accomplish in the argument, regardless of how one evaluates the grammar point?

Accepted Answer

Whatever one thinks about how technical the singular/plural argument is, Paul’s move in v.16 accomplishes a clear argumentative goal: it narrows the promise to a specific fulfillment in Christ. That supports his larger claim that the promise has its own God-given shape and endpoint and therefore cannot be redefined by the later law (v.17). By identifying the “seed” as Christ, Paul also sets up how others can be related to Abraham’s promise through Christ, which fits the broader discussion in Galatians 3 about who truly shares in what was promised to Abraham.

Question 7

How do verses 15–18 function as a hinge between the earlier and later parts of Galatians 3?

Accepted Answer

These verses connect what Paul has already argued with what he is about to argue. Earlier (3:6–14) Paul has emphasized Abraham’s believing response and Scripture’s testimony about blessing. Here (3:15–18) he adds a time-order argument: promise first, law later, and the later law cannot cancel the earlier promise. Immediately afterward (3:19–22) Paul will address why the law was given at all. So 3:15–18 sets boundaries: it insists that the law’s role must be explained in a way that does not overturn the promise or make inheritance depend on the law.
