Christians have a tendency to fall into two views. One view is that faith and salvation is 100% grace and works are not involved at all. The other view is that salvation is by grace plus works. However, the Bible is very clear that salvation is by grace through faith. It is a gift of God. However, there are also passages that tell us that works are a vital and necessary part of our salvation. Please read this edifying devotional by Martin Luther. I believe it gives us a very accurate description of works and their role in our salvation.
