salvation

"You say that you cannot overcome your besetting sin; that you have tried, and failed; that the temptation comes so unexpectedly and so strong that you cannot resist it. Let me tell you what that sort of talk really means, and perhaps you will change your tone."

Since the Sabbath is the sign of a perfect creation completed, and by the cross of Christ a new creation is accomplished, the Sabbath must be the sign of the cross. Try it and see if it is not.
