I disagree with this sentiment, as I don’t feel the lost are our enemies in the sense you’re thinking of. Here’s what I’m drawing from:

“Ephesians 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.”

“1 Corinthians 10:4-5 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;”

Our real enemies reside in the spiritual realm, and it is they who heavily influence the actions of man on a daily basis. Too often the lost serve as unwitting pawns in a devilish game. This is a sobering truth that is emphasised throughout scripture, and one we shouldn’t lose sight of as we interact with the world we live in.

Consequently, we embrace psychology instead of Biblical teaching about man’s nature. Instead of disciplining and instructing our children (per Deut 6:7, Prov 13:24, etc), we worry about their self esteem and try all sorts of techniques that God did not tell us about, because psychology tells us these things are true.

Instead of believing that the lost are just sinful, we make them out to be victims of their circumstances, because the sciences of psychology and sociology tell us these things are true.

Instead of reading and believing the first several chapters of Genesis, we embrace a lot of unbiblical conclusions about the age of the earth, evolution, early civilizations, and so on, because biology, geology, etc., tell us these things are true.

I am painting with very broad strokes here. These are just some examples, perhaps not even good ones. I’ll even go so far to say that there are exceptions. A blind application of Proverbs 13:24 might well provoke your child to wrath (Eph 6:4); the exact application of discipline will depend on the child and the situation and the context. But these are just sweeping generalities. Not everyone who claims “all truth is God’s truth” would embrace evolution. I don’t mean to imply they would; these are just some examples.

The other objection I have is that we tend to want to severely restrict the spheres in which the Bible speaks authoritatively, in order to make human science more authoritative. When I say that the Bible is inerrant, I mean that it is authoritative in more than just spiritual matters. I believe the Bible speaks to pretty much every sphere that deals with people. Granted, it won’t tell me how to write clean code. But it does have a lot to say when it comes to psychology, child rearing, government, economic systems, welfare, families, and so on. It’s also authoritative in sciences such as geology, biology, archaeology, and so on.

When the Bible does not speak directly or indirectly, then certainly I agree. We are to love God with our minds as well as our hearts. He gave us minds to think with, and a universe to explore. As long as we do not set our efforts up in contradiction to God’s revelation, then science is a very good thing.

And, while I support the war on Iraq and a pretty interventionist US foreign policy, my purpose in this post is not to wonder about the morality of the Iraq war or any physical war.

Christ was pretty militant and vocal against some categories of sinners who actively tried to keep people from the kingdom of God by the worldview they pushed. They taught that one could earn God’s favor through good works, and anyone embracing that worldview was necessarily damned. It’s quite understandable that He would vocally oppose them.

Paul dealt similarly with an entirely different crowd in Romans 1. He said they were “worthy of death”. I believe the people he railed against in Romans 1 are closer to the world view Christians have to defeat today.
