What is it that uses up our brain cells? What dominates in our minds? Where does it take us mentally? Let’s make sure it’s godly!
IF it is not godly (if it takes us into mental sin), then do this:
Proverbs 6:5 Free yourself, like a gazelle from the hand of the hunter, like a bird from the snare of the fowler.
 Allow no sleep to your eyes, no slumber to your eyelids.
 How long will you lie there, you sluggard [quit wasting time and brain cells]? When will you get up from your sleep [realize how important it is to make it right–right NOW]?
Of the seven things that the LORD hates (verses 16-19), it is the fourth one that scares me to death:
[18a] a heart that devises wicked schemes,
Why? Because if we allow our minds to build a scenario of sinful activities, we are training ourselves to sin. Where is God in that?! How can we think on godly things while entertaining sin in our minds? Does it not grieve the Holy Spirit?
King David knew the importance of training the mind:
Psalms 119:2 Blessed are they who keep his statutes and seek him with all their heart.
 Turn my eyes away from worthless things; preserve my life according to your word.
 I lift up my hands to your commands, which I love, and I meditate on your decrees.
 I have sought your face with all my heart; be gracious to me according to your promise.
 Oh, how I love your law! I meditate on it all day long.
 How sweet are your words to my taste, sweeter than honey to my mouth!
[127-128] Because I love your commands more than gold, more than pure gold, and because I consider all your precepts right, I hate every wrong path.
[131-133] I open my mouth and pant, longing for your commands. Turn to me and have mercy on me, as you always do to those who love your name. Direct my footsteps according to your word; let no sin rule over me.
[147-148] I rise before dawn and cry for help; I have put my hope in your word. My eyes stay open through the watches of the night, that I may meditate on your promises.
 Great peace have they who love your law, and nothing can make them stumble.
Jesus thinks keeping our minds guarded is important:
Matthew 5:27-28 “You have heard that it was said, ‘Do not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.” NOTE: David fell away from guarding his mind and thoughts and fell into sexual sin with Bathsheba. We must be diligent and vigilant!
Paul gave us some good guard rails pertaining to our thought habits:
Philippians 4:8 Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.
Let’s get started, shall we?!
