Holiness is a key theme in the Bible, woven throughout both the Old and New Testaments. In Christian theology, holiness refers to the absolute purity, righteousness, and moral perfection of God. It also denotes the spiritual and moral purity that believers are called to embody, reflecting God’s character in their thoughts, words, and actions. To be holy is to be set apart, consecrated, and devoted to God. This concept is deeply tied to sanctification—the process by which believers are transformed into the image of Christ, growing in purity and righteousness through the power of the Holy Spirit.
The Bible teaches that holiness is not merely an external display of righteous actions but an internal transformation of the heart, mind, and spirit. Holiness, as revealed in Scripture, is not optional for believers; it is a command from God. In fact, holiness is one of the most significant aspects of a Christian’s calling and walk with God. The pursuit of holiness is not only about avoiding sin but about actively living in a way that pleases God, setting ourselves apart for His purposes, and seeking His presence in our lives.
In this article, we will explore 15 verses that speak to the importance of holiness, the call for believers to live holy lives, and the nature of God’s holiness. These verses provide guidance on how Christians can strive to be holy as God is holy, drawing us closer to Him and reflecting His divine nature.
15 Verses About Holiness
1. Leviticus 11:44-45
“I am the Lord your God; consecrate yourselves and be holy, because I am holy. Do not make yourselves unclean by any creature that moves along the ground. I am the Lord, who brought you up out of Egypt to be your God; therefore be holy, because I am holy.”
In this passage from Leviticus, God commands the Israelites to consecrate themselves and live holy lives because He Himself is holy. The call to holiness here is not just a call to moral purity but a call to reflect the nature of God in their lives. Holiness is a reflection of God’s character, and His people are to emulate this character in their conduct. The distinction of being “set apart” is central to this passage, as God declares that His holiness is the reason for the holiness required of His people.
2. 1 Peter 1:15-16
“But just as he who called you is holy, so be holy in all you do; for it is written: ‘Be holy, because I am holy.'”
In these verses from the New Testament, Peter echoes the command found in Leviticus. He writes to Christians, reminding them that God’s holiness is the standard for their lives. Holiness is not only about moral behavior but also about living with an awareness that all of life is to be lived in reverence to God. The phrase “in all you do” is important—it suggests that holiness should affect every area of life, from our relationships to our work, our leisure to our worship. Holiness, therefore, is a lifestyle that stems from an ongoing relationship with a holy God.
3. Hebrews 12:14
“Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord.”
The writer of Hebrews stresses the urgency of pursuing holiness. This verse teaches that holiness is not only necessary for a close relationship with God but also for seeing Him in His full glory. The pursuit of peace with others and the pursuit of holiness are intertwined. The call to holiness is not an isolated endeavor but one that impacts how we relate to others. Holiness leads to peace, and peace is a necessary condition for true holiness. This verse emphasizes that without holiness, there can be no communion with God.
4. 1 Thessalonians 4:3-7
“It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control your own body in a way that is holy and honorable, not in passionate lust like the pagans, who do not know God; and that in this matter no one should wrong or take advantage of a brother or sister. The Lord will punish all those who commit such sins, as we told you and warned you before. For God did not call us to be impure, but to live a holy life.”
Here, Paul writes to the Thessalonians, urging them to live in purity and holiness. This passage highlights the importance of sanctification and personal holiness, particularly in areas such as sexual morality. The command to avoid lustful behaviors and to honor others in relationships is a practical outworking of holiness. Sanctification, which is a process of being set apart and made holy, is part of God’s will for believers, and it requires a commitment to living in a way that reflects His purity and righteousness.
5. Matthew 5:48
“Be perfect, therefore, as your heavenly Father is perfect.”
In the Sermon on the Mount, Jesus challenges His followers to aspire to the perfection and holiness of God. This verse reveals that holiness is not just about external actions but about aligning the heart with the nature of God. While perfection in this life is unattainable, the call to grow in holiness and become more like God in our thoughts, desires, and behaviors is clear. The perfection Jesus speaks of is a completeness or maturity in our relationship with God and in our Christlike conduct.
6. Romans 12:1-2
“Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship. Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing, and perfect will.”
Paul’s call to offer our bodies as a living sacrifice is a profound invitation to embrace holiness. Holiness, in this context, involves both the body and the mind. The body is to be offered to God as a living sacrifice, set apart for His purposes, and our minds must be renewed so that we no longer conform to worldly patterns but are transformed into the likeness of Christ. Holiness is not just about abstaining from sin but also about actively choosing to live in a way that pleases God, aligning ourselves with His will.
7. Ephesians 4:22-24
“You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness.”
In this passage, Paul describes the transformative work of holiness as putting off the old self and putting on the new self, created to be like God in true righteousness and holiness. This process involves a renewed mind, which leads to a changed life. Holiness is not merely about avoiding sin but about actively pursuing the righteousness of God and embracing the new nature that comes through faith in Christ. The believer’s identity is now tied to God’s holiness, and their lives should reflect that reality.
8. 2 Corinthians 7:1
“Since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.”
This verse underscores the importance of purification in the life of a believer. Purity, both of the body and the spirit, is essential for the pursuit of holiness. The command to “perfect holiness” is a call to continuously strive for spiritual maturity and moral excellence. This process involves not just outward actions but also a deep reverence for God, acknowledging His holiness and responding with a life that reflects His purity.
9. Psalm 29:2
“Ascribe to the Lord the glory due his name; worship the Lord in the splendor of his holiness.”
In this verse from Psalms, the psalmist calls the people to worship God in the splendor of His holiness. Holiness is not only a quality of God but is also central to how we approach Him in worship. The holiness of God is glorious and awe-inspiring, and true worship flows from an understanding of God’s purity and majesty. Worship is an appropriate response to God’s holiness, and it invites us to reflect His holiness in our own lives.
10. 1 John 3:3
“All who have this hope in him purify themselves, just as he is pure.”
This verse speaks to the purifying effect of the hope of Christ’s return. The believer’s hope in Christ leads to purification and holiness, as they seek to reflect the purity of Christ in their own lives. The standard for holiness is Jesus Himself—He is pure, and those who have the hope of His return are motivated to pursue purity and holiness, transforming their lives in preparation for His coming.
11. Isaiah 6:3
“And they were calling to one another: ‘Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.'”
In this powerful vision of God’s holiness, Isaiah encounters the seraphim proclaiming God’s holiness in a triune declaration: “Holy, holy, holy.” This repetition emphasizes the perfection and utter transcendence of God’s holiness. The holiness of God is central to His glory, and the whole earth is filled with the evidence of His glory. The proclamation of God’s holiness invites the believer to stand in awe of His majesty and respond with worship.
12. Revelation 15:4
“Who will not fear you, Lord, and bring glory to your name? For you alone are holy. All nations will come and worship before you, for your righteous acts have been revealed.”
The holiness of God is a key theme in the book of Revelation, as it is in the worship that takes place in the heavenly realm. Here, the holiness of God is directly linked to His righteous acts, which have been revealed to the world. The holiness of God evokes awe and worship, and one day, all nations will bow before Him in recognition of His holiness.
13. Colossians 3:12-14
“Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness, and patience. Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you. And over all these virtues put on love, which binds them all together in perfect unity.”
In these verses, Paul outlines how believers should live in light of their holy calling. Holiness involves cultivating virtues like compassion, kindness, humility, and patience. These qualities reflect the holiness of God and promote unity within the body of Christ. Holiness is not a solitary pursuit but is demonstrated in the way believers relate to one another in love and forgiveness.
14. 2 Peter 3:11-14
“Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives as you look forward to the day of God and speed its coming.”
Peter reminds believers that their hope in the coming of the Lord should inspire holy and godly living. As the world awaits its final transformation, believers are called to live with holiness, reflecting the character of God and anticipating the fulfillment of His promises.
15. Titus 2:11-14
“For the grace of God has appeared that offers salvation to all people. It teaches us to say ‘No’ to ungodliness and worldly passions, and to live self-controlled, upright, and godly lives in this present age, while we wait for the 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 wickedness and to purify for himself a people that are his very own, eager to do what is good.”
The grace of God, which brings salvation, also teaches believers how to live holy lives. The work of Christ in redeeming believers from sin and purifying them for His own possession is a key motivation for pursuing holiness. This passage highlights that holiness is a result of the grace of God and is an essential aspect of the Christian life as believers look forward to the return of Christ.
Conclusion
Holiness is at the heart of the Christian life. It is both a reflection of God’s nature and a calling for all believers. Throughout the Bible, we are reminded that holiness is not optional but a command and a privilege. It is the result of God’s transforming work in our lives and should be evident in our actions, attitudes, and relationships. As we pursue holiness, we draw nearer to God and reflect His character to the world. The verses explored in this article provide a framework for understanding what holiness is, why it matters, and how we can live holy lives in a fallen world. Holiness is not just about avoiding sin; it is about being set apart for God’s purposes, seeking His presence, and living in a way that honors Him.
