Every thought changes your brain. Thoughts change the actual physical structure of the brain. The physical structure in turn effects what you can do.
For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, and being ready to punish all disobedience when your obedience is fulfilled. (2 Corinthians 10:4-6)
We would be wise to manage our thoughts so that our brains can be physically wired to help us be obedient to God.
A path has been set before us to walk in. Change your brain to help you stay on track and keep your balance.
