In this universe that God created there is not one speck of neutral territory. There is no neutral ground. The non-believer is not neutral and we shouldn’t be. Neutrality is a myth. Man was made to worship. He either worships the true God or he worships an idol. The question is not IF the non-believer worships but WHAT He worships.
In fact, according to Romans 1, there really is no such thing as a "non-believer." There are just those whom God has plainly and "clearly" made known His "his invisible attributes, namely, his eternal power and divine nature," (so that they are "without excuse") and yet they suppresses that truth in unrighteousness. (Romans 1:18-23) They are not innocent and neutral bystanders who don't have enough evidence to believe in God. They don't WANT to believe in God and they are in rebellion to Him.
Jesus said: “Whoever is not with me is against me, and whoever does not gather with me scatters.” (Matt 12:30) Clearly, no one is neutral. You are either with Him or against Him. No one is on the fence. You are either a friend or an enemy of God. No one has a neutral cell in their entire body.
This philosophy of neutrality is why evolution is so acceptable. As Oliver Wendell Holmes said, “Nothing is certain but change.” Everything is changing and evolving therefore you cannot be certain of anything. You cannot judge or be intolerant because nothing in life is certain or constant. You must remain neutral. The problem is that those who preach neutrality are not neutral. They want us to be neutral but they are not.
The call to toleration is simply applying the neutrality principle to moral issues. But as we know, the Christian is never given equal tolerance. We’re told to be more tolerant and yet we are not tolerated. As Tom Beaudoin, assistant professor of religious studies at Santa Clara University put it: “Generation X is not tolerant of an Intolerant God.”
We are told in Rom 14:23 that "...whatever is not from faith is sin.” There is no neutrality; it is a myth. We are also told in Scripture to "think God's thoughts after Him." We, as Christians, must THINK as Christians and not neutral observers. No area of life is neutral; even your intellect must surrender to the authority of God. This is why 1 Cor 10:31 says, “So, whether you eat or drink, or whatever you do, do all to the glory of God.”
You are either for God or against Him. As Greg Bahnsen wrote: "...no middle ground – men simply are not “neutral”. Men will either follow the world or the Word. They either have the mind of Christ (1 Cor 2:16; cf. Eph 4:23-24) or a mind of futility (Eph 4:17). His thoughts are either “captive” to Christ (2 Cor 10:5) or “hostile” to Him (Col 1:21)."
