Meaning of John 17:19

In John 17:19, Jesus declares, "For them I sanctify myself, that they too may be truly sanctified," revealing a profound act of self-dedication for the sake of his followers. This statement occurs within Jesus' High Priestly Prayer, a pivotal moment in the Gospel of John where Jesus intercedes for his disciples and for all believers. The term "sanctify" (Greek: hagiazō) carries a dual meaning: it signifies being set apart for a holy purpose and being purified or made holy. Jesus' sanctification of himself is not an act of becoming holier in nature, as he is already divine and inherently holy, but rather a consecration of himself, setting himself apart from his own earthly existence and ultimately to the sacrificial death on the cross, for the express purpose of enabling the sanctification of his followers. This act is the ultimate expression of his love and obedience to the Father, laying the foundation for the spiritual transformation of those who believe in him.

Context and Background

This verse is situated within the Upper Room Discourse and Jesus' High Priestly Prayer in John chapters 13-17, specifically in the chapter 17. This prayer is Jesus' final address to his disciples before his arrest and crucifixion. It is a deeply intimate and theological moment where Jesus prays for his disciples, for future believers, and for the unity of the church. The act of sanctification here is directly linked to Jesus' impending sacrifice. He is setting himself apart, consecrating his very being and life, to be offered as the ultimate atonement for sin. This is not a passive setting apart but an active offering.

Key Themes and Messages

• Sacrificial Love: Jesus' willingness to sanctify himself for his followers underscores the immense depth of his love and his commitment to their well-being, even unto death.
• Mediatorial Work: Jesus acts as the mediator between God and humanity. His sanctification is the means by which believers are brought into a right relationship with God.
• Empowerment for Holiness: The sanctification Jesus undergoes is not merely for himself but is the very source and model for the sanctification of believers. It empowers them to live lives set apart for God.
• The Purpose of the Cross: This verse highlights that the crucifixion is not just an event but a purposeful act of consecration for the redemption and spiritual transformation of humanity.

Spiritual Significance and Application

The spiritual significance of this verse is immense. Believers are called to be sanctified, meaning they are to be set apart from the world and dedicated to God. This sanctification is not a human achievement but a divine work initiated by Jesus' sacrifice. It involves a process of progressive sanctification, where believers, empowered by the Holy Spirit, are continually being made more like Christ. The application for believers is to understand that their holiness is a direct result of Christ's offering. It calls for a response of gratitude and a commitment to live a life that reflects this divine setting apart, embracing obedience to God's will and separation from sin.

Relation to the Broader Biblical Narrative

This verse is intrinsically linked to the overarching biblical narrative of redemption. From the Old Testament sacrifices foreshadowing Christ's ultimate sacrifice to the New Testament emphasis on the transformative power of the Holy Spirit, John 17:19 encapsulates the climax of God's redemptive plan. Jesus' self-sanctification is the fulfillment of the Levitical priesthood and sacrificial system, where the high priest and the sacrifices were themselves consecrated. It is the pivotal act that makes possible the new covenant and the indwelling of the Holy Spirit, enabling believers to live a life of holiness.

Analogies

• The Consecrated Offering: Imagine a priest in the Old Testament who himself was sanctified and set apart to offer a lamb for sacrifice. Jesus is both the High Priest and the perfect sacrifice, consecrating himself to offer himself for the sins of the world.
• The Foundation of a Temple: Jesus' sanctification is like laying the foundation of a sacred temple. This foundation, though hidden, is essential for the entire structure (the church, the community of believers) to be built upon and to stand holy before God.
• The Source of a Pure River: Jesus' sacrifice is the source from which the pure waters of sanctification flow, cleansing and revitalizing all who drink from it.

Relation to Other Verses

This verse resonates with numerous other biblical passages:

• Hebrews 9:13-14: "For if the blood of goats and bulls, and the ashes of a heifer sprinkled on those who are unclean consecrate for the purification of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God." This passage directly parallels the idea of Christ's sacrifice as the ultimate purification and consecration.
• 1 Corinthians 6:11: "And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God." This verse highlights the salvific and sanctifying work of Christ and the Spirit in the lives of believers.
• Ephesians 5:25-27: "Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish." This passage uses a similar metaphor of Christ's redemptive act leading to the sanctification of the church.
• 1 Thessalonians 4:3: "For this is the will of God, your sanctification: that you abstain from sexual immorality." This verse speaks to the ongoing command for believers to live lives of holiness, a command made possible by Christ's initial sanctification.
