Change Requires Growth
For the grace of God has appeared, bringing salvation for all people, training us to renounce ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in the present age, waiting for our blessed hope, the appearing of the glory of our great God and Savior Jesus Christ, who gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works” (Titus 2:11-14, ESV).
NOT SURPRISINGLY GROWTH requires action. Acts 17:28 indicates we must be “in Christ” to mature as believers: “For in him we live and move and have our being” (ESV). Our growth as Christians is predicated upon knowing who we are in Christ; what His death, burial, and resurrection makes accessible to us. Having made a decision to accept Jesus as Messiah, we are to choose living in a manner that brings glory to God. No longer are we wandering the wilderness in search of meaning and purpose. We begin a new life, made possible through Jesus Christ. Fundamentally, we have been justified in the Father’s eyes. Redemption opens the door for reconciliation, restoration, and sanctification. Each of these components fall under the umbrella of “salvation.” It is here that we are able to adjust our sites and head in a completely different direction than when we were living in sin.
Holiness in the Old Testament is primarily in relation to God. “Exalt the LORD our God, and worship at his holy mountain; for the LORD our God is holy” (Psa. 99:9). Divine sacredness and holiness is God’s essential nature. He is morally perfect, and His holiness is manifest in total purity. By purposeful association, God’s people are holy; not because of any virtue they possess but simply by God’s special calling. Notwithstanding the above, there was an increasingly strong emphasis on moral holiness under the Old Covenant. A central feature of the Day of Atonement was inward cleansing (see Lev. 16:30). Of course, there is no less emphasis on God’s holiness in the New Testament. Under the New Covenant, holiness moves from an outward (or “corporate”) quality to believers made holy inwardly. As Christians, we are clothed in the righteousness of Christ, but we must strive to enter into true holiness (see Heb. 10:10). This is holiness as it pertains to transformation. Paul writes, “Since we have these promises, beloved, let us cleanse ourselves from every defilement of body and spirit, bringing holiness to completion in the fear of God” (2 Cor. 7:1).
This is what Paul wrote about in his letter to the Romans: “For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith for faith, as it is written, ‘The righteous shall live by faith'” (Rom. 1:16-17). Our progress must begin with redemption—without which we cannot be clothed in the righteousness of Christ. Spiritual progress is intricately linked with sanctification. It is through sanctification that we become more like Christ, aligning ourselves with the will of the Father. God is able to accomplish His will in us as we mature in our Christian walk. The Hebrew word qdš and the Greek word hagias apply to any person, place, occasion, or object that has been “set apart” from common secular use to a divine purpose. Sanctification is the ongoing impact of the Holy Spirit in our lives as believers (1).
Sanctification is not mere moral transformation (we cannot “behave” ourselves toward holiness). We are set on the path of sanctification through the redemptive sacrifice of Christ. This is a sort of spiritual “athleticism,” which denotes aiming for fitness of service; i.e., being worthy of one’s call. Amazingly, sanctification sets the stage for positive consecration of our personality (2). (Personality refers to individual differences in patterns of thinking, feeling and behaving.) It is easy to confuse holiness and sanctification. However, holiness represents purity before God, as in our being clothed in the righteous of Christ. Through the atonement of Christ’s death, we are justified and set apart for service. But sanctification is much more than being made right in the eyes of the Father; it includes God being able to accomplish His will in us as we mature in Christ. What of this idea of “sinless perfection.” Paul discusses putting on the new self in the third chapter of Colossians, which is accomplished by setting our minds on things that are above and not on things of the earth (3:2). He writes, “Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry” (3:5). Instead, as God’s chosen ones, we are to put on a heart of compassion, kindness, humility, meekness, and patience. God does not require perfection from us, but He does expect us to strive for spiritual maturity.
A New Starting Point
Through sanctification, our character, affections, and behavior change as we put on the mind of Christ. Sanctification includes a change in our total personal ethics. Of course, this is an ongoing process. At the moment of conversion we surrender self-rule. In sanctification, we relinquish what I call the habitual, premeditated practice of sin. We are bound to fail, but we need not feel condemned. Paul addresses this issue: “Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin. There is therefore now no condemnation for those who are in Christ Jesus” (Rom. 7:24-25; 8:1). The doctrine of justification by faith is an analytical explanation of God’s pardon. Justification establishes Christianity as a religion of grace and faith. It is helpful to remember that dying with Christ (redemption and justification) and living with Christ (sanctification) are both paramount to living according to the will of God.
We are to wean ourselves from worldly pleasures and pursue godliness. Paul said we must strive for spiritual perfection “until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes” (Eph. 4:13-14). Although redemption is instantaneous, sanctification is an ongoing process. The more we strive to be like Christ, the easier it becomes to deny the flesh and instead walk in the Spirit. I have learned that as I mature in Christ my sins become more painful and obvious. The Holy Spirit convicts me regarding any ungodly behavior. Because sin starts as a thought, I also ask Him to help me think about what I am thinking about. (This is called metacognition in psychology.) Paul said, “I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but 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. 12:1-2).
Peter writes, “…preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ. As obedient children, do not be conformed to the passions of your former ignorance, but as he who called you is holy, you also be holy in all your conduct, since it is written, You shall be holy, for I am holy” (1 Pet. 1:13-16). Because our mind is the battlefield on which Satan wages war, it is important to be prepared for warfare. (see The Power of Spiritual Armor.) Sanctification is the first step. Hebrews 12:14 says we must strive for holiness. White says, “This is the most common understanding of sanctification, the growth in holiness that should follow conversion” (see Eph. 1:4) (3). Paul told the Thessalonians to be sanctified wholly—keeping spirit, soul, and body sound and blameless. Everything is to be sanctified (see 1 Tim. 4:4-5). White notes that sanctification is not a mere addendum to justification and redemption. Rather, he believes our forgiveness of sins has a moral force, creating in us the will to do good. Paul distinguished his “real” or spiritual self from his fleshly self in Romans 7. Henry writes, “Compared with the holy rule of conduct in the law of God, the apostle [Paul] found himself so very far short of perfection, that he seemed to be carnal” (4).
Progress Not Perfection
Clearly, our goal as Christians is striving to live a life that is beyond reproach. Remember, this does not imply living a sinless existence, which is impossible. Instead, we are to avoid the habitual, premeditated practice of sin. Habitual sin relates to a temptation we have chosen to hang on to, ostensibly because it brings us some degree of pleasure or escape. In the sermon on the mount, Jesus taught us about brokenness, selflessness, charity, humility, peace, and righteousness (see Matt. 5). He reminds us that we are to be salt and light in the world. Jesus concluded his sermon with these words: “You therefore must be perfect, as your heavenly Father is perfect (Matt. 5:48). The beatitudes describe the Father’s attributes. Jesus instructs us to strive for a Christian life that mimics the character of God. The Amplified Bible says, “You, therefore, will be perfect [growing into spiritual maturity both in mind and character, actively integrating godly values into your daily life], as your heavenly Father is perfect.”
Paul instructs us to walk in a manner worthy of the life to which we have been called, doing so with all humility, gentleness, patience, love, peace, and mercy, bearing with one another. Spiritual maturity involves putting off “the old self” and putting on the new, created after the likeness of God in true righteousness and holiness (see Eph. 4). When we become Christians, we are not merely “remodeled” or added to. Instead, we are transformed. In other words, we don’t have two separate natures as Christians. We have one new nature—that of Christ our Lord. Our old self died on the cross with Christ, and through the resurrection we have become new. When the Father looks upon us, He no longer sees our multitude of sins. Instead, he sees the righteousness of Christ. Paul said, “…you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God” (1 Pet. 1:23). We are to put on the new self, created after the likeness of God in true righteousness and holiness (see Eph. 4:24).
And Now What?
How do we accomplish the daunting task of putting on the mind of Christ? We need to realize that God is not expecting us to become Christ or to live perfectly. Rather, our lifestyle should point others to Christ. We must think differently about sin, about God, and about Jesus. Our orientation should be away from worldly and sinful lusts. As believers, we should not be attracted to evils of this world. John said, “Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride of life—is not from the Father but is from the world” (1 John 2:15-16). MacArthur writes, “To say that a person can come to Christ without making a break from the world is a lie. There must be a change of lifestyle” (5). We come to Jesus through repentance, but it is sanctification that allows us to serve Him. We are to be imitators of Christ (see Eph. 5:1). Conversion includes renewal of mind and heartfelt repentance. These elements are needed if we are to do a 180 and walk away from sin. It is dependent on grace, and involves the infusion of new life. Evangelical theologians describe two sides to conversion: the divine invitation and the human response. It is the means by which we are resurrected from spiritual death. Bloesch says, “It also includes the Spirit’s continuing work in purifying us of discord and [our stubborn refusal to comply], remolding us in Christ’s image” (6).
Spiritual maturity is an expected result of conversion. In fact, conversion begins our ascent to Christian perfection. We shall not remain the same person we once were, but shall become a new creation (se 1 Cor. 5:17). Our true relationship with God is made evident in our lifestyle and conduct. This is what is meant by having a heart for God; getting God out of our heads and into our hearts. Peter tells us, “His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence, by which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire” (1 Pet. 1:3-4). He followed up with an admonishment to “…put away all malice and all deceit and hypocrisy and envy and all slander. Like newborn infants, long for the pure spiritual milk, that by it you may grow up into salvation—if indeed you have tasted that the Lord is good” (1 Pet. 2:1-3).
We are called upon to be mature believers in Christ. This is not possible without learning who we are in Him and walking accordingly. Redemption opens the door for reconciliation, restoration, and sanctification. Sanctification sets the stage for radical change, even to the core of our personality. We are set on the path of spiritual maturity. Although we cannot hope to be perfect while in our corruptible bodies, we are expected to strive for spiritual maturity. Jesus gives us a glimpse of the character of God in His sermon on the mount. Meekness, brokenness, humility, purity of heart, righteousness—these and other attributes are provided as a guide to becoming “perfect” as the Father is perfect. Paul instructs us to wean ourselves from worldly pleasures and pursue godliness, which is critical to our spiritual maturity. We can never become Christ, but we are called to emulate His life and ministry. This is how we become salt and light to the world. It is how we strive for spiritual maturity.
