If Paul had not been successful in his argument for justification by faith alone, Christianity would have remained a sect within Judaism, rather than becoming the universal way of salvation. Galatians, therefore, is not only Luther's epistle; it is the epistle of every believer who confesses with Paul, "I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me" (Galatians 2:20).
Ikiwa Paulo hakuwa amefaulu katika majadiliano yake kwa kuhesabiwa haki kwa imani pekee, Ukristo ungalibakia dhehebu ndani ya Uyahudi, badala ya kuwa njia ya wokovu kwa wote. Wagalatia, kwa hivyo, si tu waraka wa Lutha; ni waraka wa kila muumini ambaye anakiri na Paulo: "Nimesulubiwa pamoja na Kristo, lakini ni hai; wala si mimi tena, bali Kristo yu hai ndani yangu; na uhai nilio nao sasa katika mwili, ninao katika imani ya Mwana wa Mungu, ambaye alinipenda, akajitoa nafsi yake kwa ajili yangu "(Wagalatia 2:20).
