When wild horses are driven into a corral, they are hemmed in and no longer free. The free roamers are stopped in their own pursuits of lawlessness. We do the same thing by bringing our thoughts captive. 

Have you ever allowed your mind to wander? Where does it lead? It is futile thinking that is worthless. Philippians 2:5 says, “Let this mind be in you which was also in Christ Jesus.” The Lord disciplines us as His children. Hebrews 12:11 says, “Now no chastening seems to be joyful for the present, but painful; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it.” In your mind underline ‘have been trained.’

Bringing our thoughts captive requires training. It is not a once done endeavor. Our thoughts are controlled by choice. When a rogue thought comes, the Holy Spirit will check us. If we heed Him, we will immediately switch the undisciplined rogue thought to one that would glorify the Lord. Another way is recorded in Psalm 15:2. It says, “He who…speaks the truth in his heart.”
