What does “take every thought captive” mean?

There are many false teachings that go against the gospel of grace (Acts 20:24).  In 2 Corinthians 10:3-5, we’re told to combat these false teachings by taking every thought captive. We’re invited to make every thought obedient to Christ. This means we make the conscious decision to reject lies and embrace the truth of God’s grace. This keeps the finished work of Christ in focus in our attitudes and belief systems.
