Cognition—knowing and understanding the truth—is the first step in pursuing spiritual growth through the Word of God. After cognition comes conviction. As we learn the truth of Scripture, we must begin to develop beliefs into convictions. Our lives are controlled by our convictions. As the truth of God’s Word begins to occupy our minds and shape our thoughts, it will produce principles that we desire not to violate. This is what sanctification is about—being inwardly compelled to obedience.

We don’t want to remain spiritual children, perpetually stuck in infancy. We don’t want to be weak, vulnerable, and immature. Nor do we want to be ignorant about God’s truth, because we want to fully glorify Him for everything He has done. We want to appreciate Him in all His fullness, knowing and loving Him thoroughly. If that’s the goal, then how do we get there? How do we respond to the Word in a way that drives that progress?

I see three definitive steps in the biblical pattern of sanctification. The first is cognition. John 17:17 gives our Lord’s prayer: “Sanctify them in the truth; Your word is truth.” We have to understand what the Bible says and what it means if it is going to produce growth in us. Sanctification begins with spiritually renewing the mind, that is, changing how we think. We need “the mind of Christ” (1 Cor. 2:16). There is no premium on ignorance or naivete in sanctification. The discipline of putting the truth constantly at the forefront of our minds is crucial.

If we lack spiritual maturity, we must read everything we can that faithfully and accurately explains the Word of God to us. We must study the Bible and memorize it; we must read commentaries from biblical scholars, listen to sermons from faithful expositors, and read the biographies of godly saints whose lives display the kind of maturity we want to see in our own lives. We must soak our minds in the Scriptures, fueling the Spirit’s sanctifying work.
