What you THINK determines what & how you DO.
One of my favorite scriptures is Philippians 4:8. It's so powerful in it's simplicity.
"Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things."
I don't know about you, but I can have a lot of thoughts run through my brain that are the very opposite of the things in this verse. & that's been especially true this last year & a half.
But guess what, we have the ability (& the commission) to change the way we think! It's time to renew our minds to the Word. We can't always control the thoughts that run through our minds, but we sure can stack the deck in our favor.
(Someone's) Mama always said: garbage in, garbage out.
If you want to start to take control of your thought life, start to take control of what your eyes see & your ears hear. Spend more time in front for the Bible than in front of the TV, internet, games, or even other books.
I'm not saying you have to cut out all non-Christian material from your life, but how bad do you want it?
It's a simple "formula."
Spend time in the Word. The Word brings faith, and as faith grows so does your thought life. It is an automatic response to the living Word. Don't leave your mind to it's own thoughts, take control of the foundation. Your mind doesn't become renewed simply by catching every bad thought that runs through it, but rather by filling it with truth & giving yourself something to fight with!
It's not a one-time-flip-a-switch-cure-all, it's a lifestyle & a life-line. God didn't leave you to battle alone. He gave you the tools & the more you use the tools, the more you realize God is bigger than the enemy we face.
Tools can't build anything while they are laying on the ground. So pick them up & start renewing your mind. It'll be the best resolution you ever made.
