Meditation is something that we all do often. Worry is the perfect example of this, however we are to meditate only on what is right. 2 Corinthians 10:5 says “We are destroying speculations and every lofty thing raised up against the knowledge of God, and we are taking every thought captive to the obedience of Christ.”
(1) “Speculations” is the Greek logismos, “calculation, reasoning, reflection, thought” and in this context it refers to wrong thinking or reasoning and is connected to those thinking processes and attitudes that usurp God’s viewpoint and stand against the knowledge of God and what that should do to and in our lives.
(2) We see that Paul and his co-workers were committed to destroying and dealing with any such thinking in their lives because it was so destructive to their ability to wage war against the enemy and carry out God’s purpose as soldiers of the cross. The suggestion is that this is a daily battle, an ongoing process without which we are unable to obey and serve the Lord. He uses a military term, “taking captive” (aichmalotizo) plus the present tense which point to this as a continual struggle and warfare.
(3) The battle concerns our minds in both the content of our minds and in the way we think with our minds, the human devices of our minds which are so often influenced by Satan. “Thoughts” is the plural of noema, “mind, thought, purpose, device, design.” It is used of the schemes or devices of Satan in 2 Corinthians 2:11and of the effects of his work on the minds of men (blinding, in 4:4).
(4) Finally, we see that this affects our obedience to Christ. If we do not bring our thoughts captive, control them and order them according to the Word, the mind of Christ, we cannot live in obedience. The goal and result of every thought captive is obedience to the Lord.
So, meditating on the Word, internalizing and personalizing the Scripture, is a crucial part of the Christian life. It becomes part of the means by which we can bring every thought captive to Christ.
The importance of this is further seen in the Psalms, particularly, Psalm 119. Six times the Psalmist prays for understanding and three other times he speaks of the understanding which comes from the Word: Psalm 119:27, 34, 73, 125, 144, 169. Thus, eight times in this Psalm, we read of him meditating on the Word that he might better understand the Scripture and apply it to his life (Psalm 119:15, 23, 27, 48, 78, 97, 99, 148).
