PART III: DISCIPLESHIP AND SANCTIFICATION – GROWING IN CHRIST
Overview: Learning to Follow Jesus in Every Area
Discipleship is the lifelong journey of following Jesus Christ in every area of life. It is the natural and necessary continuation of true conversion. While justification is a once-for-all declaration of righteousness through faith, discipleship is the progressive transformation of character through obedience, learning, and perseverance.
Discipleship integrates spiritual formation, ethical transformation, and relational maturity. It is more than belief in Jesus—it is imitation of Him. It requires intentionality, surrender, and endurance, calling the disciple to submit their thoughts, desires, decisions, and habits to Christ’s lordship.
Discipleship is both personal and communal. Individually, believers are called to abide in Christ, study His Word, and walk in the Spirit. Communally, they are called to grow within the context of the local church—through accountability, service, and shared mission. Christ calls His followers into a covenant community, not into isolation.
Discipleship is not limited to religious observance; it affects every domain—home, vocation, relationships, finances, and public witness. It is the call to bring all of life under the reign of Christ.
Scriptural Foundation: Matthew 28:19–20; Luke 14:25–33
Matthew 28:19–20, the Great Commission, is the foundational mandate for discipleship:
“Go therefore and make disciples of all nations… teaching them to observe all that I have commanded you.”
Here, discipleship includes not only conversion and baptism, but lifelong obedience to Christ’s commands. The Church’s mission is not merely to make converts but to form mature disciples who know, love, and obey Jesus—and reproduce the same in others.
Luke 14:25–33 portrays the cost of discipleship. Jesus warns:
“Whoever does not bear his own cross and come after me cannot be my disciple.”
This passage makes clear that following Jesus requires self-denial, cross-bearing, and renunciation of rival allegiances. Discipleship means prioritising Christ above family, possessions, and personal ambitions. Without cost, discipleship becomes sentimental and hollow.
Together, these texts affirm that discipleship is not optional or peripheral—it is central to Christian identity. It is the path of the cross, leading not to comfort but to conformity with Christ.
Doctrinal Themes: Discipleship and the Cost of Following Christ
1. Discipleship: A Life of Imitation and Obedience
Discipleship involves progressive sanctification—growth in holiness through obedience to Scripture and dependence on the Spirit. It includes both:
- Instruction – being grounded in biblical truth;
- Imitation – modelling one’s life after Christ and mature believers (1 Corinthians 11:1).
To be a disciple is to live under the authority of Jesus and conform every area of life to His Word. This includes thoughts, behaviours, relationships, goals, and desires.
2. The Cost of Discipleship: Dying to Self
The cross is the defining symbol of discipleship—not only Christ’s death, but the believer’s daily death to self-interest, worldly priorities, and sin. To follow Christ is to reorder one’s life around the kingdom of God, even when it results in discomfort, rejection, or suffering.
The cost may include:
- Reputation loss, persecution, or even martyrdom;
- Sacrificing dreams, comforts, or ambitions;
- Daily struggle against sin and self-centeredness.
Yet, the reward far surpasses the cost—fellowship with Christ, spiritual fruitfulness, and eternal joy.
3. Discipline and Formation
The word disciple shares its root with discipline. Discipleship involves training, correction, and growth. Through Scripture, prayer, fasting, service, and fellowship, the disciple is shaped into the likeness of Christ. These are not religious performances, but means of grace that deepen intimacy with God and form godly character.
Reflection: What Habits Are Helping or Hindering My Growth?
This chapter invites sincere reflection on one’s journey of following Christ:
- Am I actively following Jesus, or am I content with nominal belief?
- Do I prioritise intentional spiritual practices, or am I shaped by convenience and culture?
- Are there relationships, habits, or ambitions that hinder my growth in Christlikeness?
- Am I engaged in a local church, where I am both discipled and discipling others?
- Do I regularly count the cost of discipleship, or have I settled into comfortable faith?
Discipleship is not automatic. Growth in Christ requires daily decisions, intentional surrender, and humble dependence upon the Spirit. The aim is not merely to know more about Jesus, but to become like Him—to walk in His steps, share His heart, and participate in His mission.
Though the road is narrow and the cost is real, it leads to life, joy, and the eternal presence of the One who calls us to follow.
