God’s formula for healthy minds is given in Philippians 4.8:
“Finally brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, let your mind dwell on these things.”
Conversely, it may also be said:
You cannot think carnally and live spiritually.
You cannot think fearfully and live courageously.
You cannot think courageously and live fearfully.
You cannot think bitterly and act kindly.
You cannot think kindly and act bitterly.
You cannot think despairingly and live victoriously!
Joy, happiness, well-being, contentment, and confidence indicate a state of mind, an attitude produced in our own thinking. It is not dependent upon the circumstances surrounding us, but rather develops from that which is within us.
Christianity is a religion of the heart – a refocusing of the mind. It is a yearning to live aloft, above the profane and mundane. It is acquiring a hunger for God and for His holiness. And it all starts with where we allow our minds to dwell.
