“As the one who called you is holy, you yourselves be holy in all your conduct, for it is written, ‘You shall be holy, because I am holy’” (1 Peter 1:15-16).

This is not a casual suggestion. It’s a direct call, echoing Leviticus 19:2, where God commands His people to be holy because He is holy. It’s an invitation to reflect His character, to be set apart, distinct, and marked by His righteousness. But how do we live this out, and why does it matter?

Holiness often feels unattainable. We might picture it as perfection, a state we can never achieve, but that’s not the full story. Holiness is about alignment—aligning our lives, thoughts, and desires with God’s will. It’s less about flawless performance and more about being devoted to God, letting His Spirit transform us from the inside out.

Living out this call means being intentional in how we conduct ourselves, not conforming to the patterns of this world but being transformed by the renewal of our minds (Romans 12:2). It’s in the small, everyday choices: speaking truth instead of lying, showing kindness instead of retaliation, pursuing purity in a culture that celebrates indulgence. Holiness isn’t just about avoiding sin; it’s about actively pursuing God’s heart.

Why does this matter? First, it matters because God’s holiness defines who He is. To be His people means reflecting His nature. Our lives are meant to point others to Him, and holiness is the light that shines through us. Second, it matters because holiness brings freedom. Sin enslaves, but holiness liberates us to live as we were created to. Third, it matters because it’s a foretaste of eternity. In heaven, we will dwell with God in perfect holiness; here on earth, we begin that journey now.

This call isn’t easy, but it isn’t one we bear alone. God doesn’t ask us to muster holiness from our own strength. He equips us through His Word, His Spirit, and His grace. As Peter reminds us, we have been born again through the living and enduring Word of God (1 Peter 1:23). This new birth empowers us to grow in holiness, craving the pure milk of the Word so we may mature in our faith (1 Peter 2:2).

The call to holiness is not a burden but a privilege. It’s an invitation to draw near to God, to be transformed by His presence, and to reflect His glory in the world. Today, let’s ask ourselves: In what ways can I align my heart and actions with His holiness? Where do I need to surrender and let His Spirit work in me?

“You shall be holy, because I am holy.” It’s not just a command—it’s our identity as children of the living God.
