I'm really enjoying Greg Bahnsen's Always Ready. It's one of those books where you say, "Why haven't I read this sooner?"
He emphasizes the danger of thinking we can be neutral in the life of our intellects. As Christians, every thought must be taken captive to Christ:
To become a Christian one submits to the Lordship of Christ; he renounces autonomy and comes under the authority of God's Son. The One whom Paul says we receive, according to Colossians 2:6, is Christ Jesus, the Lord. As Lord over the believer, Christ requires that the Christian love Him with every faculty he possesses (including his mind, Matt.22:37); every thought must be brought captive to the obedience of Christ (2 Cor. 10:5).
Consequently, when Paul directs us to walk in Christ after the same fashion in which we received Him, we can see at least this much: the Christian walk does not honor the thought patterns of worldly wisdom but submits to the epistemic Lordship of Christ (i.e. His authority in the area of thought and knowledge).
