Therefore the law was our tutor to bring us to Christ,

....  that we might be justified by faith (Galatians 3:24). Paul had been discussing the relationship of the Law to grace. He tells that if it were possible that a law could be given that would lead to life, God would certainly have given it, and  then righteousness (and life) would  have come from that  law (verse 21). But illustrating this possibility, the prophet Habakkuk had cried out centuries before  “plundering and violence are before me; There is strife, and contention arises.Therefore the law is powerless, And justice never goes forth” (Habakkuk 1:3, 4).  What then was the purpose of the Law?  Paul tells us elsewhere that “by the Law is the knowledge of sin” (Romans 3:20).  Now sin separates us from God (Isaiah 59:2).  And so the situation would have been hopeless had not God provided a way, the way of justification (being made right with God) through faith.  Then in this morning's verse Paul further explains that the Law was given to help us see the need of a different way, and that seeing,  we might embrace the good news of the gospel, and come to Christ as our saviour.  

So then the Law will neither fix injustice, nor through it can we gain salvation. But we do not for that reason throw out the whole thing. We are not free to commit murder just because we are not under Law but under grace. Civil law in the West is based upon Biblical laws and principles. And civil law needs to be enforced.  But just as the Mosaic Law did not bring justice, neither can civil law bring in righteousness and equality. Bigger government is not going to do this.  What needs to happen is that men's and women's hearts need to be changed.  But also, however just as we don't throw out the Mosaic Law because, among other things, we need is guidance. So neither can we rely on alone the Lord changing hearts to change the world.  We need the guidance of just civil law. And as Christians we need the right mixture of working towards social justice, and preaching the gospel so that men's hearts will be changed, and injustice dealt with.  

Father, Jesus preached the gospel and fed the poor.  And if we are to be balanced we need to be concerned with injustice,  but also in bringing the good news to this wicked and hurting world.  We are so often out of balance Lord, we need Your help to get there and stay there, and we are asking for this help this morning Lord in Jesus Name Amen
