The Law Was Our Tutor

Galatians 3:21-25(NKJV)

21Is the law then against the promises of God? Certainly not! For if there had been a law given which could have given life, truly righteousness would have been by the law. 

22But the Scripture has confined all under sin, that the promise by faith in Jesus Christ might be given to those who believe. 

23But before faith came, we were kept under guard by the law, kept for the faith which would afterward be revealed. 

24Therefore the law was our tutor to bring us to Christ, that we might be justified by faith. 

25But after faith has come, we are no longer under a tutor.

This is an interesting turn of phrase.  Not sure exactly what it means but let me take a shot at it. 

Before we receive the Holy Spirit we need to receive Jesus.  Since Jesus wasn't around back then there was no way for the people to receive the Holy Spirit so God gave then the law to guide them. 

Once we accept Jesus we get the Holy Spirit to guide us and we have no further need of the law?  I don't know but it seems logical to me.
