Paul tells his young protégé Timothy, “Keep a close watch on yourself and on the teaching. Persist in this, for by so doing you will save both yourself and your hearers” (1 Tim. 4:16). He is reminding Timothy that the sanctification resulting in continual discipleship to Christ necessarily includes intense study of God’s Word.
Third, the study of God authenticates and fuels worship. True Christians are not those who believe in some vague God nor trust in vague spiritual platitudes. True Christians are those who believe in the triune God of the holy Scriptures and have placed their trust by the real Spirit in the real Savior—Jesus—as proclaimed in the specific words of the historical gospel.
Knowing the right information about God is just one way we authenticate our Christianity. Intentionally or consistently err in the vital facts about God, and you jeopardize the veracity of your claim truly to know God. This is why we must pursue theological robustness not just in our pastor’s preaching but in our church’s music and in our church’s prayers, both corporate and private.
But theological study goes deeper than simply authenticating our worship as true and godly—it also fuels this worship. We must remember what Jesus explained to the Samaritan woman at the well:
True worshipers will worship the Father in spirit and truth, for the Father is seeking such people to worship him. God is spirit, and those who worship him must worship in spirit and truth. (John 4.23–24″>John 4:23–24)
We are changed deeply in heart and, therefore, our behavior when we seek deeply after the things of God with our brains. The Bible says so: “Do not be conformed to this world,” Paul writes. “Be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect” (Rom. 12:2). The transformation begins with a renewing of our minds. As John Piper has said, “The theological mind exists to throw logs into the furnace of our affections for Christ.”
Purposeful theological study of God, as an expression of love for God, cannot help but deepen our love for God. The more we read, study, meditate on and prayerfully apply the word of God, the more we will find ourselves in awe of Him. Like a great ship on the horizon, the closer we get, the larger He looms.
