What Makes Christianity Tick

Martin Luther stood alone, like the Apostle Paul, valiantly defending the great doctrine of justification by faith, the doctrine which is at the core of Christianity. He defined a Christian as, “not somebody who has no sin, but somebody against whom God no longer chalks sin, because of his faith in Christ. This doctrine brings comfort to consciences in serious trouble.”

Paul's defence over the same issue took place some 1500 years before Luther. Paul "withstood him [the Apostle Peter] to the face" (Gal. 2:11). There was no unity here. No peace! But Paul was not the problem, though he instigated the troublous moment. It was Peter and he had to be rebuked! His behavior of separating from fellow believers on the basis of race was totally disconcerting to Gentile believers and, I might add, very dishonoring to the Lord. Paul uses the pronoun "I" twice, once in reference to Peter (2:18) and the other, to himself (2:19). In the first he points out Peter's problem of building again by his behavior what he destroyed (a legal system for approaching God). He knew better. He was saved by faith alone in Christ, not by keeping the Law - just like the Gentiles. In the second, in his own person, Paul gives us an excellent description of the mysterious life of a believer. He is crucified, and yet he lives. At the time of His salvation he was united to Jesus Christ, who now lives within the saint. The old man is crucified (Rom. 6:6), but the new man is living; he is dead to the world, and dead to the law, and yet alive to God and Christ; sin is mortified, and grace quickened. What Paul contended for is what we must today. Justification (being declared righteous by God our Judge) by faith alone makes no sense to most people. Surely, they say, we must do something about sins that remain in our lives! Paul answers this more as we will see in our continuing study of the rest of Galatians. For now he points out that he is avoiding two great difficulties:

1. That he did not frustrate the grace of God, which the doctrine of the justification by the works of the law did. "And if by grace, then is it no more of works." (Rom. 11:6)
2. That he did not frustrate the death of Christ, whereas, if righteousness come by the law, then it must follow that Christ has died in vain. Why should He be appointed to die, if we might have been saved without it?
