When Peter exhorts believers in 2 Peter 3:18 to “grow in the grace and knowledge of our Lord and Savior Jesus Christ,” he is calling them to an ongoing process of spiritual maturity. Grace is often thought of only in terms of salvation—God’s unmerited favor that brings us into relationship with Him. However, grace is not just the starting point of the Christian life; it is the power that sustains and transforms us throughout our entire spiritual journey. Ephesians 2:8 reminds us that we are saved by grace, but Titus 2:11-12 shows that grace also teaches us how to live: “For the grace of God that brings salvation has appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age.”
Growing in grace means that, as believers, we continually experience more of God’s grace in our lives. It is a dynamic process in which we deepen our understanding of God’s character and His transformative work in us. Grace empowers us not only to be forgiven but also to become more like Christ in every aspect of our lives.
Growing in grace is about inner transformation. God’s grace does not leave us in our broken, sinful state but actively works within us to renew our hearts and minds. Romans 12:2 calls us to this transformation: “And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.” Through grace, our old ways of thinking and behaving are replaced with the new life we have in Christ. Grace is the engine of this transformation, empowering us to reject sin and embrace righteousness.
This process of transformation is not instant. Growing in grace requires patience, humility, and a willingness to allow God to work in us over time. Philippians 1:6 encourages us with the promise that God is committed to this transformative work: “being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ.” As we grow in grace, we trust that God is continually at work, shaping us into the image of His Son.
Peter pairs the concept of growing in grace with growing in knowledge: “grow in the grace and knowledge of our Lord and Savior Jesus Christ.” To grow in grace is to grow in a deeper understanding of who Jesus is and what He has done for us. Colossians 2:6-7 echoes this call to growth: “As you therefore have received Christ Jesus the Lord, so walk in Him, rooted and built up in Him and established in the faith, as you have been taught, abounding in it with thanksgiving.” Knowledge of Christ is not merely intellectual; it is relational. It involves growing in intimacy with Him, understanding His heart, and following His ways.
As we spend time in God’s Word, prayer, and worship, our knowledge of Christ deepens, and with it, our experience of grace expands. 2 Peter 1:3 tells us that “His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue.” Growing in grace means that we lean into this divine power, drawing closer to Christ, and allowing our relationship with Him to shape every area of our lives.
Growing in grace does not mean that we will never struggle with sin, but it does mean that grace gives us the power to overcome it. Romans 6:14 says, “For sin shall not have dominion over you, for you are not under law but under grace.” Grace not only forgives us but also equips us to live in victory over sin. As we grow in grace, we experience greater freedom from the sinful habits and patterns that once held us captive.
This victory over sin is a process. 2 Corinthians 3:18 describes the gradual nature of this transformation: “But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.” Growing in grace means that with each passing day, as we behold Christ, we are being changed to reflect His character more fully. Grace empowers us to fight against sin, not in our own strength but through the power of the Holy Spirit working within us.
As we grow in grace, the evidence of this growth becomes visible in our lives through the fruit of the Spirit. Galatians 5:22-23 lists this fruit: “But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control.” These qualities are the natural result of God’s grace at work in us. As we grow in grace, we grow in our ability to love others, to live with peace and patience, and to exhibit kindness and self-control.
The fruit of the Spirit is not something we produce on our own; it is the result of abiding in God’s grace. John 15:4-5 makes this clear: “Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.” Growing in grace means staying connected to Christ, the source of all spiritual life, and allowing His grace to bear fruit in us.
One of the most powerful ways we grow in grace is through trials and sufferings. It is often in the most challenging times that we experience the depth of God’s grace in new and profound ways. 2 Corinthians 12:9 reveals this truth: “And He said to me, ‘My grace is sufficient for you, for My strength is made perfect in weakness.’” In our moments of weakness and difficulty, God’s grace sustains us, giving us the strength to endure and the peace to trust in His plan.
Growing in grace means learning to rely on God’s grace in the face of adversity. James 1:2-4 encourages us to view trials as opportunities for growth: “My brethren, count it all joy when you fall into various trials, knowing that the testing of your faith produces patience. But let patience have its perfect work, that you may be perfect and complete, lacking nothing.” Through grace, trials become moments of spiritual growth, where we are refined and strengthened in our faith.
As we grow in grace, we grow in humility. The more we experience God’s grace, the more we realize our dependence on Him. James 4:6 reminds us, “But He gives more grace. Therefore He says: ‘God resists the proud, but gives grace to the humble.’” Humility is a key to growing in grace because it acknowledges that we cannot live the Christian life in our own strength. We need God’s grace every day, in every situation, to guide us, strengthen us, and transform us.
Growing in grace also involves recognizing that everything we have and everything we are is because of God’s grace. 1 Corinthians 15:10 says, “But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me.” Grace not only saves us but empowers us to serve God and others. It humbles us by showing that all of our accomplishments and spiritual growth are the result of God’s work in us, not our own efforts.
As we grow in grace, our hearts are filled with gratitude and worship. We recognize that everything we have—our salvation, our spiritual growth, our ability to overcome sin, and even our endurance in trials—comes from God’s grace. Hebrews 12:28 calls us to respond to grace with worship: “Therefore, since we are receiving a kingdom which cannot be shaken, let us have grace, by which we may serve God acceptably with reverence and godly fear.” Our response to grace should be a life of worship, lived in reverence for the God who has lavished His grace upon us.
Gratitude becomes the hallmark of a life growing in grace. Colossians 3:16-17 encourages us, “Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him.” As we grow in grace, our lives become an offering of thanksgiving to God, reflecting His grace through our words, actions, and attitudes.
Growing in grace is not a one-time event but a lifelong journey of transformation. 2 Peter 3:18 calls us to continually grow in grace and in our knowledge of Christ, recognizing that grace is the power that sustains and shapes us into the image of Jesus. As we deepen our understanding of grace, we experience its transformative power in our lives, leading to victory over sin, the bearing of spiritual fruit, endurance through trials, and a heart of humility and gratitude. Ultimately, growing in grace draws us closer to God and makes us more like Christ, reflecting His love and holiness to the world around us.
