“Diversity and division is infinitely more precious than a satanic unity. The problem God’s people are facing today: Satan wants unity in what? — in error. God would infinitely prefer division because of truth. Do you know what Jesus said in Matthew 10? He said, ‘I have come not to bring peace, not to bring unity, but to bring division, to set a son against his father, a daughter against her mother, so that people within their own households will be enemies of each other.’ That is what Jesus said he came to do … God’s smashing of satanic ecumenical unity was an incredible blessing [Genesis 11: the Tower of Babel] … The potential for satanic depravity is infinite, as long as what continues? — a unity in error — organized blasphemy. Measure this friends. Grasp it. Satan will, in his brief hour, at the end of this world, be given his opportunity to demonstrate what total unity is like in the human race, when every person will have a mark on the forehead or right hand, and will walk lockstep under incredible blasphemy …

“You say, ‘We want unity.’ Oh, really? What kind of unity? ‘We want all the churches to get together.’ Oh, really? You mean in error, in confusion, in heresy? That is, dear friends, the ecumenical movement of our hour, in which all the great denominations and all the great church leaders are becoming more and more unified. In what? — in compromise and theological error; and this is the ultimate horror.”

“Again, men tell us that our preaching should be positive and not negative, that we can preach the truth without attacking error. But if we follow that advice we shall have to close our Bible and desert its teachings. The New Testament is a polemic book almost from beginning to end … It is when men have felt compelled to take a stand against error that they have risen to the really great heights in the celebration of the truth”
