What does John 6:64 mean?
What is the meaning of John 6:64?

However

Jesus’ words in verse 63 have just underlined that “the words I have spoken to you are spirit and they are life.” Yet He instantly introduces a contrast:

• “However” (or “But”) signals that not everyone standing there is receiving that life.

• It brings both comfort—because the promise is sure—and warning—because rejecting the promise is real (cf. Matthew 7:21-23; Hebrews 3:12).

• The Lord is candid: spiritual vitality is not automatic, even for those who have heard His teaching and seen His miracles.


there are some of you

• The phrase zeroes in on people within the visible circle of disciples, not the hostile crowd or the distant religious leaders (John 6:60-61).

• It reminds us that outward association with Jesus—listening, following, even calling oneself a disciple—can mask an unchanged heart (1 John 2:19).

• The wording shows pastoral concern: Jesus is addressing them personally, giving opportunity for repentance.


who do not believe

• “Believe” in John always carries the weight of trusting, receiving, and resting in Christ (John 1:12; 3:16).

• Some had eagerly sought physical bread (John 6:26) yet balked at embracing Him as the Bread of Life (John 6:35).

• True belief is more than admiration; it is surrender (John 8:31-32). The verse exposes the fatal difference between curiosity and conversion.


(For Jesus had known from the beginning)

• His knowledge is perfect and timeless. From the first moment they joined the group, He knew every motive (John 2:24-25).

• This omniscience highlights His deity (Psalm 139:1-4) and assures us nothing surprises or thwarts Him.

• Believers can rest in a Savior who knows the end from the beginning (Isaiah 46:9-10), while unbelief is laid bare before Him.


which of them did not believe

• The Lord’s awareness is individual, not statistical. He can single out each unbelieving heart (John 10:14).

• He continues to extend truth and grace even to those He knows will reject it, displaying patience (2 Peter 3:9).

• Salvation, then, is never the result of fooling Jesus but of surrendering to Him (John 15:16).


and who would betray Him

• The specific traitor is Judas Iscariot (John 6:71; 13:11).

• Prophecy is being fulfilled: “Even my close friend…has lifted up his heel against me” (Psalm 41:9; Acts 1:16).

• Jesus’ foreknowledge does not cancel human responsibility; Judas remains morally accountable (Matthew 26:24).

• The mention of betrayal here foreshadows the cross, showing that God’s redemptive plan is on course and unwavering.


summary

John 6:64 reveals a Savior who speaks life-giving words, yet frankly acknowledges that some listeners remain in unbelief. It portrays:

• The sobering reality that not all disciples are true believers.

• Christ’s omniscience, seeing every heart from the outset.

• The sovereignty that weaves even betrayal into God’s saving purposes.

Belief, therefore, is not mere exposure to Jesus but wholehearted trust in Him—the Bread that truly satisfies.
