The law is good. It is our schoolmaster to bring us to the point of revealing our sin. But, the law can not redeem. If it could we would not have had to have Christ come to earth for the atonement He made. The law is the fore-shadowing of Christ. Christ's atonement and the indwelling of His Spirit through the means of the Holy Spirit gives us a greater means of sanctification. Heb 8:13 with chapter 9. There is a purpose of the Old law, but a better one motivated by love.

@KarMarJo57 good post. I heard an old interview with Ravi Zacharias that I liked where he said, "The law is like a mirror. It shows me who I am. It reveals my reflection, but it can't change me. For that I need Christ." Without the law I cannot see that I am lost. Without Christ I cannot change.
