If it was, we would have something to boast about. Some people think grace and works are a team that together bring salvation to a person. This was a misconception that was prevalent in my day. Many, like myself had our roots in the Mosaic Law. But works and grace don't go together to get salvation or to keep salvation.
Works are a product of salvation.
Salvation is received by calling on the name of the Lord Jesus Christ. That is the way I was saved. All this is done through the faith of the operation of God.
