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

Paul is speaking of a situation that did not exist to emphasize that the inheritance came only by means of the promise. AT: "the inheritance comes to us by means of the promise, because we could not keep the demands of God's law" (See: rc://en/ta/man/translate/figs-hypo)

inheritance

Receiving what God has promised believers is spoken of as if it were an inheritance of property and wealth from a family member, and eternal blessings and redemption. (See: rc://en/ta/man/translate/figs-metaphor)
