Off the mark. Religion saves no one. The blood of Jesus Christ saves anyone. But anyone must accept the Grace. The blood of The Christ is not a religion, it is a cure, a cure for the poison of sin. The Word of God tells you that it is God Who is in you both to will and do of His good pleasure. BUT He is in only those who accept His unmerited Grace, His Life in their spirit.
So, action is required. The grace by itself isn't sufficient in your theology.
