Because God knows how powerfully He designed our minds to be, He commands us to take great care in what we allow our minds to dwell upon. One hundred billion neurons strong and able to make two hundred calculations per second, the mind is designed to think great thoughts and do marvelous things. It is a force, God tells us, that will determine our personal destinies.
The defining marker for God’s man is that he thinks deeply and continuously about what God has spoken. and just as plain pork ribs take on a new identity as they soak in a special marinade, so the man who immerses himself in God’s Word takes on the very character of God; he is changed into someone new.
Be careful how you think, because your thoughts run your life. (PROVERBS 4:23, NCV, emphasis added)
