What has recently impressed me is how fiction [and its visual presentation through electronic media] is mixed with nonfiction in our culture. It is to the point that it seems that some people’s minds operate almost entirely in the realm of the unreal. That is dangerous. I read sometime ago a debate about whether what we watch with our eyes affects us, and a larger percentage of those that participated thought that it did not—but God’s Word says, “As a man thinketh in his heart, so is he.” In other words, we indeed are what we think about. It is interesting how much Scripture has to say about our thinking.
Here are a few examples: “Be not conformed to this world: but be ye transformed by the renewing of your mind” (Rom. 12:2). “Bringing into captivity every thought to the obedience of Christ” (2 Cor. 10:5). “Be renewed in the spirit of your mind” (Eph. 4:23). “Let this mind be in you, which was also in Christ Jesus” (Phil. 2:5). “Finally, brethren, whatsoever things are true, whatsoever things are honest . . . think on these things” (Phil. 4:8). “Set your affection [margin: mind] on things above” (Col. 3:2).
“Gird up the loins of your mind” (1 Peter 1:13).
