God in His great wisdom has determined that He will bring the nations to serve Him, and He will do so as His people gather together to hear His Word preached, and to eat and drink His Word served.
As the enemies of God rail and blaspheme, our interest is to make sure that we are not the cause of the blasphemy through any sins we have committed, and to follow that up with a careful refraining from ungodly responses to whatever they do. That said, there is nothing left for us to do but to sit down at the Table God has prepared for us in the presence of our enemies.
This meal is a glorious meal, and it has a potency far beyond our calculation. It is not the potency that some superstitious Christians have sometimes imagined for it—as though God were interested in performing magic tricks with the food. Manners are important. We are not here to play with the food, and our divine host does not play with the food either. Rather, He uses the food to nourish and strengthen His people.
The Word has been proclaimed. The gospel is heard by us, and we hear it with faith. Because of this, and only because of this, the meal we approach now is a great blessing, and not a curse for us. But what is that blessing? It is that we are privileged to conquer the world simply by eating what God has set before us. And though the nations rage, and the heathen imagine a vain thing, there is nothing whatever they can do about it. There are no counter-measures against this.
