Just as a simple observation - we say that the Gospel gives forgiveness of sins, life, and salvation.
We get forgiveness... we understand that whole salvation. Why do we seem so worried about that life part? Now, again, don't misunderstand - this isn't some anti-law rant... but the Gospel creates and gives life, true life, life which strives to fulfill the law willingly.
Why don't we trust the Gospel. Faith works... literally - faith leads to works. That's what faith does - it clings to Christ and receives all good things from Him - including life.
