Following Monday’s post on Counterfeit Sanctification, we received a lot of good questions about the nature and assurance of true spiritual growth. Today and tomorrow, John MacArthur will address those issues.

by John MacArthur

You probably know that most people in America and many more worldwide identify themselves as Christians. But how many of them can explain and defend the gospel, articulate basic biblical theology, or live lives that support the claims of their faith? The tragic fact is that compared to the vast number of people who claim to be Christians, very few are actually growing to be more like Christ.

That process of spiritual growth is called sanctification, and it’s a vital part of every believer’s life. For the past several weeks, we’ve been looking at some popular, purported methods of sanctification—commonly called spiritual formation—and weighing them against the biblical models for spiritual growth. As we near the end of this series, I want to highlight some basic, clear teaching from Scripture about the nature of sanctification and help you properly evaluate your own spiritual growth.

It’s important to distinguish what sanctification is and is not. It is not simply feeling closer to God or experiencing His presence. It’s not a collection of secret insight and personal encouragement from Him to you. And it’s not a vague sense of subjective spirituality—in fact, it’s not measured, engaged, or informed by your emotions or feelings at all.

True sanctification, according to Scripture, is the process of God’s transforming work in your life. In the moment of your salvation, you are declared justified by the Lord through the sacrifice of His Son and freed from the guilt of sin. From there, sanctification frees you from the pollution of sin, helping you destroy sinful patterns and relinquish your former wickedness.

And just as with salvation, sanctification is not accomplished by our will or actions—it’s the work of the Lord in the lives of His people. In 1 Thessalonians, Paul prayed that the Lord would complete His sanctifying work in their lives.

Now may the God of peace Himself sanctify you entirely; and may your spirit and soul and body be preserved complete, without blame at the coming of our Lord Jesus Christ. Faithful is He who calls you, and He also will bring it to pass (1 Thessalonians 5:23-24).

The word translated here as sanctify literally means to be set apart—in its noun form it is usually translated as holiness. So in basic terms, sanctification is the Lord’s process of separating us from sin and setting us apart for holiness. Paul’s prayer is that the Lord would bring about that transformation in the lives of the Thessalonian believers—that their lives would reflect a decreasing frequency of sin and an increasing frequency of holiness.

That transformation isn’t prompted or fueled by feelings, emotions, or subjective spiritual experiences. As Paul says in Romans 6, it’s a function of your new nature in Christ.

Therefore do not let sin reign in your mortal body so that you obey its lusts, and do not go on presenting the members of your body to sin as instruments of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments of righteousness to God. . . . But thanks be to God that though you were slaves of sin, you became obedient from the heart to that form of teaching to which you were committed, and having been freed from sin, you became slaves of righteousness (Romans 6:12-13, 17-18).

Sanctification is the fruit of salvation. It’s the transforming process by which God’s people shed their past sinfulness and grow to reflect His holiness. And if you truly belong to God, you’re undergoing the process of sanctification right now.

Next time we’ll look at how to gauge where you’re at in that process.

Thanks for your great insights on such an important issue!

Here's a kids' version of the answer to "What is Sanctification," complete with the 1 Thess. 5:23-24 reference (I think even adults be helped by this song!):

Hi. At the risk of being off topic, I am not sure where baptism comes in in the process. This blog is extremely helpful for me to understand Gods amazing gift to us. Pastor MacArthur is an outstanding teacher, and I really dont know what I would do without GTY. I was baptized Catholic as an infant, but my church experience stopped when I was about 12. I was saved while in the army, but no fellowship followed that. I am 45 now and have been to a couple of different Baptist churches in the past but never became part of a congregation. I really have had no experience being part of a church, and it seems to be more and more pressing as time goes by. Anyway, can someone help me with the issue of baptism? I was baptised by the Pastor at one of the churches I went to for a short time. I love the Lord, and just have this question thats been on my mind for quite some time (among others), but this seems to be at the forefront of my mind. Thanks for anyone helping me with an answer. To clarify my question: Is baptism necessary for salvation?

Daniel (#2)

The thief crucified with Christ was not baptised in water and yet Jesus promised him that he would enter into paradise. Suppose Philip and the Ethiopian treasurer hadn't passed by a body of water (Acts8:36,37)? Your salvation is not in water. But you need to find a body of believers to fellowship with! See Pastor John's blog dated 10.26.12 and take action!
