I don't think that the law and the forgiveness that Christ offers us is that complicated. We can't earn our salvation because clearing us from the death of sinfulness is in the hands of Christ. Christ paid for our sin, and we can't do that, we are not God. But to take that fact as a reason to not work for the Lord is all completely wrong. We become Christ's child when we accept what He did for us. we are made pure and sin free. As a child of God we are to obey Him and God is against sin. As God's child we do what He tells us to and God tells us to not sin.
Some say that because of our sin state as a human person we can't obey perfectly so why try? God offers salvation after we repent, we don't go to God for forgiveness for something we intend to repeat over and over. Repentance requires turning away from sin.
