Completed Cases — Category Three: Theological Polarities
Case 7 — Grace and Law
Audience
Anyone who has read Paul's "you are not under law but under grace" alongside Jesus's "do not think that I have come to abolish the Law" and felt the need to choose between them.
The Tension
Grace: Ephesians 2:8–9: saved by grace through faith, not by works. Romans 6:14: you are not under the law, but under grace. Galatians 5:4: you who are trying to be justified by the law have been alienated from Christ. Law: Matthew 5:17–19: Jesus did not come to abolish the Law but to fulfill it. Romans 3:31: we uphold the law. Romans 8:4: the righteous requirement of the law is to be fully met in us. 1 John 2:3–4: we know that we have come to know him if we keep his commands.
The Load-Bearing Assumption
Grace and law are competing bases for the relationship with God — you are either standing on grace or standing on law. Remove this and law and grace describe different aspects of the same relationship at different stages.
What Holding Both Produces
The order is everything. Paul's consistent argument: grace is the ground, obedience is the fruit. The person who is justified by grace alone through faith is not then free to disregard the law. They are free for the first time to keep it — not from compulsion, not for justification, but as the expression of a transformed life in response to the one who rescued them. The law written on tablets is replaced by the law written on the heart (Jeremiah 31:33) — same content, different basis and different motive. Paul fights on two fronts simultaneously: against the legalist who adds law to grace as the basis of justification, and against the antinomian who uses grace to dismiss the claim of obedience. Both errors destroy the polarity by collapsing one pole.
The Connection to What Matters
Poverty of spirit is the posture that correctly locates both. The person in genuine poverty of spirit knows they cannot earn the relationship through obedience — that is grace receiving its proper weight. The same person, having received the relationship as grace, does not treat it as a license to ignore the one who gave it. Love is not performed to earn standing. It is expressed because standing has been received. The branch does not produce fruit in order to stay in the vine. It produces fruit because it is in the vine. The difference is not behavioral. It is the location of the motive.
Precedent Note
Luther's commentary on Galatians is the essential Reformation engagement. Calvin's "third use of the law" holds the obedience pole without surrendering grace.
