"Boundaries". . . . In John 10:7, Jesus famously said: "Truly, truly, I say to you, I am the door of the sheep." I cannot envision any useful purpose for having a "door [for] the sheep" if there is no sheep-pen or enclosure of some kind with well-defined, secure barricades, sturdy fences, or a protected perimeter of some kind.-Phil Johnson

"So today's evangelicals bend over backward not to sound the least bit dogmatic. Because certainty is perceived throughout our culture as a kind of cruel arrogance. Clarity, authority, careful definitions, and firmness are likewise looked upon with deep suspicion. Stating your beliefs with settled conviction is a sure way to start trouble these days. 
Want proof? Just page through our blog and read any random comment thread where 30 or more people have replied. You'll see, I think, that the most common complaint we get from angry commenters is that we sound too sure of our position—or some variation on that theme. (We're too rigid; too reluctant to change our minds; too emphatic in the way we make our case; or whatever.) We're expected to qualify and over-qualify everything we say in a way that practically nullifies every critique and ultimately countermands every concern.

 We are told we always ought to look for things to commend if ever it is absolutely necessary to criticize something, and above all, we must be brotherly to everyone who comes in Jesus' name. See: the concept of "unity" commonly touted today has nothing whatsoever to do with "being in full accord and of one mind" (Philippians 2:2). Instead, it is a broad, visible, ecumenical homogeneity without boundaries. And that is nothing like the biblical concept of unity."--Phil Johnson
