We are all fighting the same enemy. If you read through the Bible, you will find that.
Read through the subsequent history of the Christian church, and you will find that God’s people in times of persecution have always been driven together and cemented together in a much closer manner than they had ever been at any other time.

They are fighting the same common foe, so they draw together. And as Christians become fewer in number year by year in this country, it should have this effect upon us: we are aware of one another, and we draw closer together; our love for one another is increased because of our circumstances.” 

D. Martyn Lloyd-Jones
