Check out this unbelievably insightful verse in the Book of Proverbs:
“Be careful how you think; your life is shaped by your thoughts.”(Proverbs 4:23 GNT)
Long before psychology came around, God had this thing already pegged: your thoughts determine your feelings, your feelings determine your actions, and your actions determine your destiny.
It starts with how we think.
Our minds are really an amazing creation. It would take a computer the size of the Pentagon just to carry out the basic functions of your brain. Your brain contains over 100 billion nerve cells. Each individual cell is connected with 10,000 other neurons.
You are constantly talking to yourself — all the time. You’re talking to yourself right now! Research indicates that most people speak at a rate of 150 to 200 words per minute, but the internal dialogue that you carry on with yourself (self-talk) is more like 1,300 words per minute.
The problem is that in our self-talk, the overwhelming majority is negative! If you’re typical, you are your own worst critic. Right? You’re always putting yourself down. You could walk into a room smiling, but inside you’re saying, “I’m not smart enough. I’m ugly. I’m out of shape. And I’m always late.” Most of this dialogue is unconscious.
Here’s a news flash for you today: God wants you to stop putting yourself down!
When you put yourself down, who are you really putting down? You’re really pointing to the Creator who made you. When you say, “God, I’m worthless; I’m no good; I can’t do anything,” you’re actually saying, “God, you blew it with me.” That’s why God says it’s wrong to put yourself down.
How do we eliminate that kind of self-talk? It’s NOT by trying really hard to not think that way. That never works. Negative thoughts can’t be simply removed, they have to be replaced.
Philippians 4:8 says “Finally, brothers and sisters, 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.”
Actively think of the good! Think of the goodness of God, the good that He’s placed in you, the good that He’s blessed you with, all the good! Like Paul says, if there’s anything good in your life AT ALL, think about it.
On top of that, if you’re a negative self-talk person, there really is no greater antidote than having a consistent time spent in God’s Word. Study it, memorize it, meditate on it, and apply it in your life. I can’t tell you a better thing to help you raise your confidence level than to get in the Bible and start believing what God says about you.
