Paul Now Deals With Objections To His Statement And Stresses That The Law's Purpose Is To Point To Christ (Galatians 2:17-21).
‘But, if while we have sought to be justified in Christ, we also were found sinners, is Christ made one who serves sin? God forbid. For if I build up again those things which I destroyed, I prove myself a transgressor.'
This question can be seen in two ways. Firstly as asking - ‘Surely seeking to be ‘put in the right' through Christ means that we are must first of all admit to being sinners and must declare ourselves sinners. Does this not, it is asked, therefore make Christ the one who serves sin?' This question was especially relevant to converted Pharisees. They had built up a way of life that they felt had on the whole made them ‘almost good'. They were ‘by nature Jews'. Yet the Gospel was now asking them to tear down that facade and admit their sinfulness. Was this not making them sinners?
To such a question Paul replies, ‘Of course not. On the contrary, it is if I build up again what I destroyed, if I again make the Law pre-eminent, that I make myself a lawbreaker and a sinner. It is the Law that shows me where I have gone wrong and accuses me of breaking the Law'. And the more I try to observe it the more I fail. Thus if we are to speak of something as ‘promoting sin' it is the Law that does that. And to revive it is therefore to promote sin. See for a particular example of this Romans 7:7-8.
Alternately, relating to the context, the question might be seen as asking, ‘If we seek to be justified in Christ and thus abandon the ritual requirements by which we have lived as you are demanding, thus becoming in the eyes of Jews ‘sinners', does this not mean that Christ is acting as a servant of sin and promoting sin?' The reply is the same. It is that by again bringing in the Law I multiply sin, for it is the Law that reveals sin. Outside the Law such things are not all sinful, but once I come under the Law sin multiplies, for I see it for what it is.
The problem for the Judaisers was that they thought that Christ's sacrifice made present atonement for their sins, as animal sacrifices had before Jesus had died, and that after that their salvation depended on their maintaining their position by observing the Law in all its forms. Jesus had thereby become to them a super-sacrifice, a help along the way, and nothing more. And it left them in the same predicament as they had been in before. How were they to keep the Law perfectly? Paul rejects this. He says quite plainly that to take up that attitude is actually to encourage sin (compare Romans 7:8-11), for they can only fail, thus leading on to further failure, and taking them down the road to despair. He knew it because he had walked that way himself.
But how very different was the offer of the Good News made through Christ. For those who come to Christ can ignore the requirements of the Law as far as their position before God and their eternal salvation is concerned. Instead they simply trust in what He has done for them on the cross. They accept that He died for them. They accept that He has borne their sin in their place as ‘a ransom in the place of many; (Mark 10:45). And then they accept that because He has died in their place, they can go free. They are forgiven, and their sins are no longer counted against them, because they had been paid for by Christ.
But does this therefore mean that people can go on sinning as they like. He lets us know that the answer to that question is a resounding ‘No!' based on the significance of the cross. And he now explains that significance.
