By this everyone will know that you are My disciples,This phrase emphasizes the distinguishing mark of Jesus' followers. In the context of the Last Supper, Jesus is preparing His disciples for His departure. The "this" refers to the love they are to show one another, which serves as a testimony to the world. Historically, the early Christian community was known for its love and unity, which set it apart from other groups. This love is not merely an emotion but a commitment to act in the best interest of others, reflecting the sacrificial love of Christ. The phrase also connects to
Matthew 5:16, where Jesus speaks of letting one's light shine before others.
if you love one another.”
The conditional "if" indicates that love is the essential evidence of true discipleship. This love is agape, a selfless, unconditional love that mirrors the love of Christ. In the cultural context of the time, such love was countercultural, as society was often divided by class, ethnicity, and religion. The command to love one another is a recurring theme in the New Testament, seen in passages like 1John 4:7-8, which states that love is from God and those who love are born of God. This love is a fulfillment of the law, as Paul writes inRomans 13:10, and is a reflection of the new covenant relationship established by Jesus.

By this- Jesus sets the standard right at the outset. “By this” signals one unmistakable mark He is about to reveal, not a collection of optional virtues (John 15:14).
- The focus is narrow and intentional, as if the Lord is saying, “Pay full attention; what follows is the defining test.”
- It echoesExodus 12:13 where a single sign—the lamb’s blood—distinguished God’s people. So here, one sign marks true discipleship.
everyone will know- The witness is public, not private. When love flourishes among believers, outsiders perceive something genuine (Acts 2:46–47).
- “Everyone” includes skeptics, critics, and seekers alike. Love is universally recognizable, transcending culture or background (1 Corinthians 14:24–25).
- God’s design is evangelistic: our relationships become the sermon the world hears first (Matthew 5:16).
that you are My disciples- The identity in view is relational, not merely doctrinal. Right beliefs matter, but Jesus ties credibility to visible love (1 John 4:20–21).
- Disciples represent their Rabbi; therefore, the character of Christ must be mirrored in the community (Philippians 2:1–5).
- The phrase highlights exclusivity: love authenticates a genuine connection to Jesus, distinguishing His followers from mere admirers (Luke 6:46).
if you love one another- Love here is active, sacrificial choice, modeled moments earlier when Jesus washed the disciples’ feet (John 13:14–15).
- Practical expressions include:
• Bearing with weaknesses (Romans 15:1–2)
• Forgiving readily (Colossians 3:13)
• Sharing resources (1 John 3:17–18)
• Encouraging daily (Hebrews 3:13)
- The command targets “one another,” underscoring mutual responsibility inside the body, which then overflows outward (Galatians 6:10).
summaryJohn 13:35 teaches that Christ-appointed love is the singular badge identifying authentic disciples. When believers choose sacrificial, observable love, a watching world gains undeniable evidence that Jesus is alive and His followers belong to Him.
(35)
By this shall all men know that ye are my disciples.--The thought of their state of orphanage when He should depart from them is still present. He gives them a bond of union, by which they should always be linked to Him and to each other in the principle of love. The followers of great Teachers and Rabbis had their distinctive marks. Here was the distinctive Christian mark, which all men should be able to read. It is instructive that the characteristic mark of Christianity should thus be asserted by its Founder to consist, not in any formulary or signs, but in the love which asserts the brotherhood of man. The apologists of the first centuries delighted in appealing to the striking fact of the common love of Christians, which was a new thing in the history of mankind; and while the Church has sometimes forgotten the characteristic, the world never has. By their love for each other, for mankind, for God, is it known or denied that men who call themselves Christians are really Christ's disciples.
Verse 35. -
By (or,
in)
this shall all men know that ye are my disciples, if ye have love one toward another. Not by works of majesty and power, but by love to one another. All commentators refer to the well-known saying of St. John at Ephesus, as recorded by Jerome, "This is the Lord's commandment. If ye love one another it is enough" (Tholuck refers to Tertullian's 'Apol.,' 39; Minucius Felix, "They love before they know each other ;" and Lucian, "Their Master makes them believe they are brothers," 'De Mort. Pereg.'). Analogies to the great law of Christ may be found in the Law of Moses, in Talmudical writings, in the Confucian 'Analcets,' and in Stoical maxims; but this
ἐντολή in its fullness, and as sustained by this motive, or inspired by this pattern, and lifted to this standard, is
new to the human race: and it is the power which has revolutionized thought, society, and life. So long as this great power prevailed, the Church made astounding progress; when the so-called disciples of Christ began to hale and kill one another the progress was arrested. But, thank God, the "new commandment" has always had marvelous power over the Church of Christ.
