Commentaries:
The law plays a large part in our salvation in that it is through the law that we are revealed as sinners—that we might repent, be justified, and thus made alive to God. If the law were not there to tell us what sin is, we could never repent. If the law were not there to set the standard, we would never have anything to shoot for. If the law were not there to show us "this is the way to live," we would have no clear path as to what is right.
Thus the law, far from being done away, is there for our salvation—even though it cannot give us life, of and by itself. This ties in with Romans 7:7-9. Paul also says, in Galatians 2:20, that he "died," which needs to be connected with Romans 6:1-6. He died, then, because the law revealed that he was a sinner and claimed its due. He remained alive only because he is joined with Christ, becomeing a part of His body.
Paul rose from baptism as a symbol of Christ's resurrection, and he lived because of the faith of Jesus Christ, who made this possible by what He did. Paul's life was different than when he was striving to be justified by the law. The law can condemn and guide, but it cannot give one life. Nor can it give a person the power to keep it.

The Covenants, Grace and Law (Part 26)
This introduces us to another Protestant "ditch" we do not want to fall into. They assert that, because it is obvious that we cannot keep the law (because we sin from time to time), Christ kept it for us. "Christ did it all," they say. In so saying, they provide some with an excuse for not even trying to keep it and others with a justification for being passive and careless in their keeping of it.
In these five verses, Paul begins to show that the law is far from being done away and that we have a serious obligation to give our all in obedience to it if Christ lives in us and the fruit of God's Spirit are to be produced in our lives.

The Covenants, Grace and Law (Part 26)
Justification is clearly an act of God's grace, because what we deserve from what we have earned—from what we have done, the conduct of our lives—is death. There is none righteous, no not one (Romans 3:10; Psalm 14:1). Since justification, then, cannot be claimed as a right because we have sinned, it must be received as a gift. That fact that it is given makes it an act of grace.
It is not our hanging on to Christ (that is, the keeping of the law) that saves us, but rather Christ hanging on to us. That is, it is not what we do, but it is what He does continuously as acts of grace that saves us, because we deserve death. If we can earn salvation through law-keeping, Paul is saying in verse 21, "then Christ died in vain." If we can earn salvation through law-keeping, then Christ's sinless life and agonizing death were not necessary, because we can do it ourselves.
Justification is not vindication or exoneration. Both of those words connote that a person was right all along, but the true facts were hidden from those who were doing the judging. In some cases with men, vindication is possible because people are judged unrighteously. Their judges are not using righteous judgment.
But God never judges unrighteously! He knows all the facts. He knows our heart. He knows everything about us in every situation that we have ever been in, so He cannot vindicate us because we are not clear of guilt. He cannot exonerate us because we are not innocent. Justification is more than that. It is setting us right or calling us righteous though righteousness does not exist in us.
