For if the inheritance comes by the law, then it no longer comes by promise

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)

the inheritance

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)
