Deeper Still: What It Means to Grow in Grace and Knowledge as a Disciple

Growing in Grace Is Growing in Relationship with Christ

The call to discipleship is not merely a call to behavior change—it is a call to deep, abiding relationship with Jesus. And at the heart of that relationship is grace. Grace is the foundation of our salvation, the strength of our walk, and the atmosphere in which growth takes place. To grow in grace means to grow in our experience of God’s unearned favor, our dependence on His strength, and our reflection of His character.

2 Peter 3:18
“But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and forever. Amen.”

This final exhortation in Peter’s epistle is a call to movement, maturity, and depth. The word grow indicates that discipleship is not static—it is a continual progression into more of Christ. Grace is not just the starting point of the Christian life—it is the sustaining power of it.

To grow in grace means we learn to trust less in ourselves and more in Him. We begin to rest in His love even when we fail. We become more gracious with others as we receive grace ourselves. We lean on God’s strength in weakness, and we walk in increasing freedom from condemnation. The disciple who grows in grace grows in joy, humility, and peace.

Romans 5:2
“Through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God.”

Grace is not a one-time gift—it is the place we stand every day. Discipleship teaches us to stay in that place, to walk by grace, and to extend it to others.

Growing in Knowledge Means Knowing Jesus, Not Just Facts

Discipleship involves the mind as well as the heart. To grow in knowledge is not simply to collect theological facts—it is to know the person of Jesus more intimately. It is to understand His character, His ways, His words, and His will. True knowledge produces love, worship, and transformation.

Peter’s command is not to grow in knowledge alone—but in the knowledge of our Lord and Savior Jesus Christ. This kind of knowledge is relational, not merely informational. It’s the kind of knowledge that comes from walking with Him, listening to Him, obeying Him, and being changed by Him.

Philippians 3:8
“Yet indeed I also count all things loss for the excellence of the knowledge of Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them as rubbish, that I may gain Christ.”

Paul’s passion was not for abstract theology—it was to gain Christ. To grow in knowledge is to treasure Him more deeply, to seek His truth more fervently, and to reflect His life more fully. The disciple who grows in knowledge walks in greater wisdom, discernment, and spiritual authority.

Grace and Knowledge Must Grow Together

Grace without knowledge can lead to shallow emotionalism. Knowledge without grace can lead to prideful legalism. But when both grow together, the result is a mature, balanced, and powerful disciple.

Discipleship is the process that nurtures both. It teaches us to root our understanding in Scripture and to live our lives in response to God’s grace. It shows us how to apply truth with love, and how to walk in holiness with humility.

Colossians 1:9-10
“For this reason we also, since the day we heard it, do not cease to pray for you, and to ask that you may be filled with the knowledge of His will in all wisdom and spiritual understanding;
that you may walk worthy of the Lord, fully pleasing Him, being fruitful in every good work and increasing in the knowledge of God.”

True growth is not just measured by what we know, but by how we live. As we grow in grace and knowledge, our lives become increasingly pleasing to the Lord, fruitful in service, and aligned with His heart.

Growing in Grace and Knowledge Guards Against Deception

Peter ends his letter with a call to growth in part because the Church was facing false teaching. One of the greatest defenses against error is a growing, personal knowledge of Christ and a deep experience of His grace. Disciples who are anchored in truth and shaped by grace are not easily led astray.

Ephesians 4:14-15
“That we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting,
but, speaking the truth in love, may grow up in all things into Him who is the head—Christ.”

Growth in grace and knowledge leads to stability. Discipleship protects the Church by producing believers who are mature, discerning, and grounded in the truth. They don’t just know what they believe—they know who they believe.

Growth Is Ongoing Until Christ Is Fully Formed in Us

Peter ends his exhortation by pointing everything back to Jesus: “To Him be the glory both now and forever.” Growth in grace and knowledge ultimately leads to one result—the glory of Christ. The more we grow, the more we look like Him. The more we look like Him, the more the world sees His glory through us.

Galatians 4:19
“My little children, for whom I labor in birth again until Christ is formed in you.”

Discipleship is not finished until Christ is fully formed in us. Growth is not a phase—it is a lifelong pursuit. Grace deepens. Knowledge expands. Worship increases. Love overflows. And Christ is glorified.

Conclusion: Never Stop Growing
