Paul was concerned because some Christians were apparently being influenced by the unwholesome reasonings and philosophies promoted by Satan’s world. (Eph. 4:17-19) That can happen to any one of us. In a desperate attempt to turn us away from Jehovah, Satan, the god of this system of things, uses various tactics. One of them is that of exploiting any tendency we may have toward selfish ambition or self-promotion. He may even use certain aspects of our background, our culture, or our education to bring us over to his way of thinking. Is it possible for us to root out things that are “strongly entrenched” in our minds? (2 Cor. 10:4) Notice how Paul answers: “We are overturning reasonings and every lofty thing raised up against the knowledge of God, and we are bringing every thought into captivity to make it obedient to the Christ.” (2 Cor. 10:5) Yes, with Jehovah’s help we can actually gain control over wrong reasonings. w19.06 8 ¶1-3
