This does not exclude our responsibility to work for the purpose of sanctification. Works are not for justification but for sanctification. Works do not save us, but they are essential for transformation! To put it bluntly, we have to practice being God; we have to learn to live as God lives. Is that not how one becomes proficient at something?
God shows in many places in the Bible that He is pleased with our obedience. Our works do not save us, but they please Him (see Hebrews 13:16; Colossians 3:20; I John 3:22; etc.). He is so happy when we work at sanctification because they assist in the transformation process.
Parents ought to understand this. We are pleased by the stumbling efforts of our child to please us. So is God! He looks on our motives, intentions, and the principles involved in what His child is doing. He does not just look at the quantity or the quality—He looks at us as His children, who are trying to imitate Him.
Sanctification is absolutely necessary to prove to God our righteous character and belief in Jesus Christ.

The Covenants, Grace, and Law (Part Nine)
Paul further drives home the point that no one can earn justification or boast about having received it through his own effort. "Where is boasting then? It is excluded. By what law? Of works? No, but by the law of faith." No one can ever brag about having been so obedient or having done so many good works that God just had to grant him eternal life. No one will ever be able to boast that he "earned" his way into the Kingdom of God! All those who enter the Kingdom will have done so solely because God extended His mercy to them and forgave their sins through their faith in the sacrifice of Christ.

Saved By Faith Alone?
We are justified through faith in the sacrifice of Jesus Christ. He is the payment for our sins, thus freeing us from sin's penalty, and at the same time, God accounts—or imputes—Christ's righteousness to us. The righteousness that enabled Him to be the perfect sacrifice is accounted as if it is ours! This then makes it possible for us to have access into the presence of the holy God.
But this does not do away with law. It establishes it! It places the law in its rightful position in our understanding of what God is working out in our lives.
