When Jesus crosses paths with you, he reveals you for who you are. In response to him, people change—either making a turn for the better or taking a turn for the worse. A turn for the better means that Christian growth, or sanctification, is happening. But this is not the result of a single template of change. Because situations and persons come unscripted, fluid, and unpredictable, Jesus engages each person and situation in a personalized way. 

What are the sources of true change, and how does God work in those factors to transform your life? 

God himself changes you  

“It is God who works in you, both to will and to work for his good pleasure.” (Philippians 2:13) 

God intervenes in your life, turning you from suicidal self-will to the kingdom of life. He raises you in Christ when you are dead in trespasses and sins. He restores hearing when you are deaf (you could not hear him otherwise). He gives sight when you are blind (you could not see him otherwise). He is immediately and personally present, a life-creating voice, a strong and strengthening hand. 

All good fruit in our lives comes by the Holy Spirit. Jesus said it was better if he went away, because the Holy Spirit would come (John 16:7). The Holy Spirit continues to do the things that Jesus does— continually adding to the number of books that could be written. The stories we tell are not just about what has happened to us and what we’ve done. They are about what Jesus Christ has done as he goes about saving and sanctifying us through all our days. 

The Word of truth changes you

“The testimony of the Lord is sure, making wise the simple.” (Psalm 19:7) 

God communicates messages to us—many messages. Scripture speaks with a true voice into a world churning with false voices. Scripture reveals innumerable features of God’s person, purposes, will, promises, and actions. Scripture clarifies every facet of human experience. 

Of course Scripture and God work in harmony. In fact, all five dimensions are complementary—and all ultimately depend on the hand of God. One lovely expression of the interplay between the Word of God and the God of the Word occurs in Romans 15. Paul first points out how Scripture changes us: “Whatever was written in former days was written for our instruction, that through endurance and through the encouragement of the Scriptures we might have hope” (Romans 15:3). 

A few sentences later, Paul asks God himself to change us, to give us the very things that his Word calls for and calls forth: “May the God of hope fill you with all joy and peace in believing, so that by the power of the Holy Spirit you may abound in hope” (Romans 15:13). In Scripture, God comes in person. We participate by hearing and responding. 

Wise people change you 

“Whoever walks with the wise becomes wise.” (Proverbs 13:20) 

Godly growth is most frequently mediated through the gifts and graces of brothers and sisters in Christ. At the most basic corporate level, you can’t call on God unless you believe in him; you can’t believe in him unless you hear of him; you can’t hear of him unless someone proclaims him (Romans 10:14). Good worship, preaching, teaching, prayer, and sacraments have radiant, fruitful effects. 

Similarly, the honesty and graciousness, humility and clarity, good sense and convictions of others have radiant, fruitful effects (James 3:17–18). Good role models make a huge difference (2 Timothy 3:10–11). It is a great mercy to know people who deal gently with your ignorance and waywardness, because they know their own weakness and sinfulness, and they know the mercies of Christ (Hebrews 5:2–3). It makes a huge difference when other people are able to comfort you in your afflictions, because God is bringing comfort into their afflictions (2 Corinthians 1:4).
