How to Be a Disciple: Living for the Resurrected Jesus (A Study of John 21)
The Gospel of John is a masterclass in identity, purpose, and the transformative power of Jesus Christ. Throughout the first twenty chapters, the Apostle John meticulously builds a case to prove that Jesus is the Messiah, the one who fulfilled every requirement and command of Israel that humanity could not fulfill on its own. He shows us a Savior who went to the cross to pay for the sins of all who would follow Him. However, the story doesn't end at the empty tomb.
In John chapter 21, there is a distinct shift in the narrative. If the first twenty chapters focus on who Jesus is and the work of salvation, chapter 21 focuses on the application: What does it look like to live as a Christian after Jesus has paid for our sins? This final chapter serves as a manual for discipleship, teaching us through the restoration of the Apostle Peter that living for the resurrected Jesus demands full commitment.
The Historical Context: Why John 21 Matters Today
To understand the weight of this passage, we must look at when and why it was written. John penned this Gospel between 90 and 95 AD, roughly 60 years after the death and resurrection of Jesus. He wasn't merely collecting a book of facts; he was intentionally selecting stories to encourage a first-century audience that was struggling with intense persecution.
John wanted his readers to see how the original disciples handled their trials so that they—and we in the 21st century—would be better prepared to handle our own. In the story of Peter’s encounter with Jesus on the beach, we find three pillars of true discipleship: Loving Jesus, Glorifying Jesus, and Following Jesus.
--------------------------------------------------------------------------------
Pillar 1: Love Jesus – The Foundation of Restoration
The scene opens after a long, unsuccessful night of fishing. Peter and the disciples had returned to their old lives, perhaps unsure of what to do next despite having seen the resurrected Lord twice before. After a miraculous catch of 153 fish, they find Jesus on the shore cooking breakfast over a charcoal fire.
The Significance of the Charcoal Fire
The mention of the charcoal fire is a deliberate and symbolic detail. It was around a similar charcoal fire that Peter, in a moment of fear and weakness, had denied Jesus three times during the trial before the crucifixion. By bringing Peter back to a fire, Jesus creates a safe but somber space for restoration.
Jesus asks Peter three times, "Simon, son of John, do you love me?". These questions are intentional:
Addressing the Legacy: By calling him "Simon, son of John," Jesus emphasizes the weight and generational importance of the question.
Surpassing the Past: When Jesus asks, "Do you love me more than these?", He is likely pointing to the boat, the 153 fish, and Peter's old career. He is asking if Peter’s love for Christ surpasses his desire for his old life and comforts.
Healing the Denial: The three questions directly mirror Peter’s three denials, giving him the opportunity to publicly reaffirm his devotion in front of his friends.
Love is Not a Feeling; It’s an Action
Peter’s response has changed since the resurrection. No longer boisterous or claiming he would die for Jesus out of his own strength, Peter humbly relies on Jesus's own knowledge: "Lord, you know everything; you know that I love you".
Jesus’s response to Peter’s confession of love is a command: "Feed my lambs" and "Tend my sheep". This teaches us a fundamental truth about discipleship: Jesus receives love from us when we serve and care for His people.
True Worship: While solitude, music, and journaling are good practices, Jesus defines the ultimate expression of love as building His church and serving others.
The Ownership of the Sheep: We must remember that the people we serve are "Jesus's sheep," not our own. Whether in a local church or in our daily lives, we are caretakers of His flock.

Pillar 2: Glorify Jesus – Fulfilling the Divine Plan
If loving Jesus is the foundation, glorifying Jesus is the mission. After restoring Peter, Jesus delivers a sobering prophecy regarding Peter's future: "When you were young, you used to dress yourself... but when you are old, you will stretch out your hands and another will... carry you where you do not want to go".
The Cost of Discipleship
John notes that Jesus said this to show the kind of death Peter would undergo to glorify God. History and tradition suggest Peter was crucified upside down under Emperor Nero around 60-65 AD. This prophecy highlights a core reality of the Christian walk: as disciples, we no longer have the freedom to do whatever we want.
We often measure a "good week" by how easy or comfortable it was. However, glorifying God often involves fulfilling a plan that is challenging or even involves suffering.
The Worth of Suffering: Just as Aragorn in The Lord of the Rings fought a "hopeless" battle at the Black Gate to serve a higher purpose (distracting Sauron so Frodo could destroy the ring), disciples are called to face hard things because the cause of the Kingdom is worth the battle.
Meaningful Suffering: Suffering for Jesus is never in vain because it is part of His sovereign plan.
Finding Your Calling
Glorifying God might mean planting a church, going on a mission trip, or simply being a faithful parent.
--------------------------------------------------------------------------------
Pillar 3: Follow Jesus – Relinquishing the Agenda
The final command Jesus gives to Peter is simple: "Follow me".
This command is a call to focus. In the verses following this passage, Peter begins to ask about the fate of other disciples like John. Jesus essentially tells him that it doesn't matter what happens to others; Peter’s only job is to focus on his own walk with Christ.
The Challenge of Submission
For many, the most challenging part of discipleship is relinquishing our own plans for God’s plans. We often get angry when doors close or when life doesn't turn out as expected, but true peace comes from submitting to His will.
For the Non-Believer: The invitation is to recognize sin, trust in Jesus's perfect life and sacrifice, and begin the journey of following Him.
For the Believer: The invitation is a daily choice to submit to His direction, even when it feels like trying to "force a square peg into a round hole".

Conclusion: The Monday Morning Application
The test of a disciple is not just how they behave on Sunday morning, but how they live on Monday morning. When you wake up tomorrow, your to-do list and your own agenda will be waiting for you. To live for the resurrected Jesus, you must be intentional.
Ask yourself:
How can I love Jesus today by serving someone else?
Am I willing to glorify God by following His plan, even if it's hard?
Will I follow Him regardless of what is happening in the lives of those around me?
Living for the resurrected Jesus is not about a checklist of "Christian things"; it is about a deep, transformative relationship that shifts our focus from ourselves to His Kingdom. As we learn from Peter, the journey from denial to restoration leads to a life of profound purpose.
Will you follow Him today?
