Love Fellow Believers
In the realm of human commerce and culture, names carry immense weight. A name is more than a label; it is a repository of reputation, character, and legacy. When a brand becomes synonymous with excellence, such as the craftsmanship of a Steinway piano or the luxury of a Louis Vuitton trunk, the name itself serves as a guarantee of quality. Conversely, names associated with fraud or failure carry a tarnished identity that is nearly impossible to resurrect. This principle of identity is central to the Christian faith. To take upon the name of Christ as a disciple is to inherit a specific reputation. Scripture suggests that the primary quality defining this reputation—the singular characteristic that distinguishes the follower of Jesus from the world—is a profound and visible love for fellow believers.
The Mandate of the New Commandment
On the night before his crucifixion, during what is often called the Farewell Discourse, Jesus issued a final set of instructions to his disciples. These words were pregnant with the weight of his impending sacrifice, serving as a spiritual “swan song” for those who would carry his mission forward. In this intimate setting, he established the definitive mark of his followers: a commitment to love one another.
John 13:34-35 (NASB) ’A new commandment I give to you, that you love one another, even as I have loved you, that you also love one another. ‘By this all men will know that you are My disciples, if you have love for one another.’
At first glance, this commandment appears redundant. The call to love one’s neighbor was already central to the Mosaic Law, summarized in the core tenets of the Old Covenant. The command to love God and love others formed the foundation of Jewish ethical life for generations.
Deuteronomy 6:5 (NASB) ’You shall love the LORD your God with all your heart and with all your soul and with all your might.
Leviticus 19:18 (NASB) ’You shall not take vengeance, nor bear any grudge against the sons of your people, but you shall love your neighbor as yourself; I am the LORD.
However, Jesus identifies this command as “new” for two reasons. First, it was the first time he specifically mandated this horizontal love among his disciples as their primary corporate identity. Second, and more importantly, the standard of love was no longer merely “as yourself,” but “as I have loved you.” The person of Jesus Christ became the living plumb line, the perfect model of what this love must look like in practice.
A Love Modeled in Sacrifice
To understand the love required of a disciple, one must look to the life and ministry of Christ. His love was not a vague sentiment but a relentless series of sacrificial actions. He transitioned from the perfect union of the Trinity to the limitations of humanity, emptying himself of heavenly comforts to serve a broken world.
Philippians 2:5-8 (NASB) Have this attitude in yourselves which was also in Christ Jesus, who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, [and] being made in the likeness of men. Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross.
Throughout his ministry, Jesus demonstrated that love requires the relinquishment of rights and reputation. He associated with the marginalized, bore the mockery of the religious elite, and ultimately performed the lowliest of tasks, such as washing the feet of those who would soon abandon him. His life was defined by the principle that true greatness is found in servitude.
Mark 10:45 (NASB) ‘For even the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.’
The ultimate expression of this modeled love was the cross. Jesus taught that there is no greater manifestation of love than the willingness to lay down one’s life for others. This sacrificial posture is the standard to which every believer is called.
John 15:13 (NASB) ’Greater love has no one than this, that one lay down his life for his friends.
The Nature of Agape: Unconditional Surrender
The Greek language offers several words for love, but the New Testament writers primarily utilized agape to describe the love of God. Unlike romantic or familial affection, agape is an unconditional, selfless surrender of oneself for the benefit of another, regardless of whether the recipient deserves it or can return the favor. It is a love based on the character of the giver rather than the merit of the receiver.
In human relationships, love is often conditional, fluctuating based on emotional satisfaction or reciprocal behavior. In contrast, the love Christ demands of his disciples is a vertical gift that produces a horizontal reality. Because believers have experienced the unconditional love of God, they are empowered to extend that same grace to one another, even when it is difficult or inconvenient. This love is the fuel for the Christian life.
1 John 4:19 (NASB) We love, because He first loved us.
Love with Skin On: The “One Anothers”
Christian love must be actionable; it must, in a sense, have “skin on it.” Jesus indicated that the world would recognize his disciples not by their theological precision alone, but by the visible evidence of their care for one another. This is not a hidden emotion but a public testimony. The New Testament contains over fifty “one another” exhortations that provide a practical framework for this visible love. Believers are called to bear one another’s burdens, forgive one another, comfort one another, and live in harmony.
This communal life requires proximity and commitment. The commands of Scripture cannot be fulfilled in isolation or through a purely digital existence. Discipleship necessitates a “life-on-life” environment where believers are close enough to see each other’s needs and participate in each other’s struggles. Whether it is a community gathering to support a family in transition or a group of friends laboring together in service, these actions serve as tangible proof of Christ’s presence in the church.
The Corporate Witness and the Great Commission
The internal health of the church is the most compelling argument for the gospel to an onlooking world. While the church is called to love the lost and the outcast, Jesus specifically highlighted that the way believers treat each other serves as the primary witness. When a diverse group of people—divided by culture, background, and opinion—is united by a radical, sacrificial love, it creates a community that the world cannot ignore.
This commitment to love is the foundation of the Great Commission. A disciple is not merely a student of information but a follower who replicates the life of the Master. The call to make disciples of all nations is a call to invite others into this community of love.
Matthew 28:18-20 (NASB) And Jesus came up and spoke to them, saying, ’All authority has been given to Me in heaven and on earth. ‘Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age.’
True discipleship is bookended by love: it begins with the love of Christ that compels the believer to follow, and it results in a life that reflects that love to others. At the center of this journey is the cross, which provides the mercy and power necessary to sustain such a radical lifestyle. To be a disciple is to forsake the self-centeredness of the world and to embrace the sacrificial, unconditional, and actionable love of the Savior. In doing so, the follower of Christ maintains a “good name” that points ultimately to the Name above all names.
2 Corinthians 5:14 (NASB) For the love of Christ controls us, having concluded this, that one died for all, therefore all died;
