Confessing Christ

A favorite quotation by Martin Luther (1483-1546) regularly comes to my mind.  Actually it is on the door of my study.  He says, with his typically inimitable pungent eloquence:

If I profess with the loudest voice and clearest exposition every portion of the truth of God except precisely that little point which the world and the devil are at that moment attacking, I am not confessing Christ.  Where the battle rages there the loyalty of the soldier is proved, and to be steady on all the battlefield besides is mere flight and disgrace if he flinches at that point.

What is that point, or are those points, today?  Where is the battle raging?  How are the soldiers doing?
