It is just that these works are not combined with our faith to merit the forgiveness of our sins, they are, instead, a natural result of our saved condition. We do good works because we are Christians, not to become Christians. Additionally, being a Christian means that you are serving the true Jesus, not a false one. In order for a person to follow Jesus, he must first accurately understand who He is. If someone called their pet iguana Jesus, even though he had great faith in Jesus the iguana, his faith is useless.
Faith is only as good as the object in which it is placed.
The New Age Jesus is a man in tune with the divine consciousness. In opposition to this, the Jesus of Christianity is both God and Man. See the two natures of Jesus for more information on this. We can't fully answer these questions, but we can look into the Bible for clues to their answer. It focuses on another.
