God wants us to hear Him, to watch/worship Him, to remember the mitzvah (the instructions He has given us), receive ordinances, and study and live the Torah. And we do all these by grace. Yet there are still those that think there is a difference between grace and works.
Many say that the greatest gift God has given us is the Atonement of Christ. This makes sense, as it is this atonement that grants us the Grace that offers us salvation. However, until we accept it, this grace is merely that—and offering. Perhaps then, the greatest gift God has granted us is the freedom to choose for ourselves.
