The voices we listen to and the thoughts we allow to occupy our minds eventually shape who we become and what we do. If our goal is debauchery and depravity, we don’t have to do much—just avoid God, avoid Scripture, and avoid godly people. If our goal is a mediocre spiritual life, we can just occasionally focus on God’s Word, and the rest of the time focus on whatever else is out there. But if our goal is to have a mind that is the dwelling place of God, we need to fill it with what God says, and meditate on His Word.
