Paul, the Apostle, wrote to the Church in Corinth:
The weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ… (2 Corinthians 10.5)
Taking our thoughts “captive” simply means to be aware of what we are thinking, and exercising control over our thoughts by subordinating them to what God says; it is forming our opinions and convictions upon Scripture above any other sources of information. Even over our own experiences.
To the Romans Paul wrote similarly:
Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. (Romans 12.2)
Again, Paul is asserting the importance of thinking biblically.
As a culture, we are thinking and talking politically and sociologically about justice, but not theologically or Biblically. Perhaps this is what we ought to expect of the culture. But it is also true of the American Church. It is true of the Church, largely, because we are not, and we have not been, talking about the issues in our churches. Consequently, church members, Christians who are inundated with the socio-politcal perspective from the daily news and common rhetoric don’t have a biblcial framework through which to filter, and talk about, these issues.
