"Casting down imaginations, and every high thing that exalts itself against the knowledge of God, and bringing every thought into captivity to the obedience of Messiah;" (2 Corinthians 10:5 KMV)
Our minds tend to be completely out of control. Even those who insist theirs is not, aren't objectively aware of everything they think throughout the day. And in addition to the voice we hear "in our heads" constantly forming words, we have even more non-verbal thoughts. These include feelings, impulses, reactions, and instincts. And below this massive sea of thoughts lies too many subconscious thoughts to number. And as the Scriptures tells us, as we think in our hearts, so are we.
Some of the more popular ways to gain a little more control over your thoughts include subliminal programming and meditation. Sadly, while the principles behind these fields are highly effective, almost all of the programs of that nature that are out there today are produced from secular, and often New Age, world views.
All of our subliminal programs are based upon Biblical truths (you can even write your own script!). Our meditation course steers you toward God, not toward yourself or demons. And our relaxation audios are clean and highly effective.
Don't let your mind control you; instead, bring it into obedience!
