There is a war going on and the battlefield is your mind. Romans 12:2 says, Do not be conformed to this world...but be transformed (changed) by the [entire] renewal of your mind... (AMPC). We are in a spiritual battle, and we must fight with spiritual weapons. God has given us His Word as our main line of defense against the lies of the enemy.  Jesus tell's us in Matthew chapter 6...."take no thought." In other words, I don't have to take the negative thoughts that arise in my mind because those thoughts did not originate with me! When we do not take the thoughts, this is the path to "Winning The Battle of The Mind."
