Paul uses this argument to show that the inheritance does not come by obeying the law but by believing God's promise. Alternate translation: "If people could receive the inheritance by obeying the law, then it would no longer be true that people receive the inheritance by believing God's promise" (See: [[rc://en/ta/man/translate/figs-hypo]])
Paul speaks of what God has promised to give to believers as if it were an inheritance of property and wealth from a family member. Aternate translation: "the gift" (See: [[rc://en/ta/man/translate/figs-metaphor]])
