Verses 6-8: This is the One who came by water and blood, Jesus Christ; not with the water only, but with the water and with the blood. It is the Spirit who testifies, because the Spirit is the truth. For there are three that testify: the Spirit and the water and the blood; and the three are in agreement.
In the previous installment, the theological meaning of the water and the blood was defined as they pertain to the earthly mission of Jesus Christ. Ryrie asserts that they are the “verification of Christ’s credentials”1 as the Son of God (v. 5).
The One Who Came
Now John clarifies the influential means by which Our Lord came to fulfill His earthly ministry by emphasizing that it was “not with water only.” But, in contrast to the belief that His baptism could stand alone to validate that the Father sent Him, John maintains that it is the water and the blood that substantiate Jesus Christ’s divine mission. But this cannot be understood as truth unless the theological meaning of the water and the blood is accurately interpreted.
· The water refers to His baptism: the inaugural event of His earthly ministry, by which He fulfilled the Jewish Law prescribed by Moses for the ordination of priests (Leviticus 8:6).
- The blood refers to His violent death: the completion of His earthly ministry by crucifixion as the substitutionary sacrifice on behalf of the sins of the entire world (1 Peter 2:24; 1 John 2:2).
These inseparable events substantiate the entire earthly ministry of Jesus Christ. He came having been divinely sent by the Father by His incarnation, thus becoming the unique person of the universe, the God-Man: He “became flesh and dwelt among us” (John 1:14). It was in human flesh that Our Lord accomplished His divine mission. Again, John is confronting the widespread Gnostic heresy advocated by Cerinthus, who was mentioned in the introduction to this epistle. Cerinthus taught that Our Lord was not human but a phantom, an apparition. He denied the conception and physical birth of Jesus Christ, claiming that Our Lord had what only seemed or appeared to be a real body, yet able “to converse, to eat, to suffer, and to die.”2 These Gnostic adherents rejected Our Lord’s hypostatic union of “two distinct and dissimilar natures.”3 Instead they regarded Him as two unconnected entities: Jesus, the man and Christ, as deity/God. Lightfoot explained that they “supposed that the Christ entered Jesus at the time of His baptism and left him at the moment of His crucifixion. Thus the Christ was neither born as a man nor suffered as a man.”4
The Spirit of Truth
John’s opposition to the Gnostic heresy is centered on two particular points: first, their erroneous teachings of Our Lord’s Incarnation, claiming that Jesus was the “natural son of Joseph and Mary.”5 Secondly, their dismissal of the divine nature of His earthly ministry; encompassing His baptism to His crucifixion and everything in between, including His miraculous signs and teachings, even denying the actuality of Our Lord’s bodily resurrection from the dead and ascension into heaven.
John maintains that his truth claims are not based upon human viewpoint, as something that he personally fabricated. Instead he wisely gives proper credit to the testimony of the Holy Spirit: “It is the Spirit who testifies.” This word testify comes from the Greek word meaning “to bear witness.”6 Here the Holy Spirit is the irrefutable witness to the person and earthly works of Jesus Christ. For the Holy Spirit was instrumental in His incarnation (Luke 1:35); was at His baptism (Mark 1:10); empowered Our Lord in His works and miracles (Matthew 12:31–32) and raised Jesus from the dead (Romans 8:11).
John attests to the truthfulness of the Holy Spirit’s testimony having been told by Jesus that the promised Helper “is the Spirit of truth” (John 14:17; 15:26; 16:13). And now John amplifies Our Lord statement by declaring that “the Spirit is the truth” meaning that the Holy Spirit is the undeniable possessor and propagator of absolute truth. John believes this, and so can we.
The Three Witnesses
In verses 7 and 8, John declares that in fact there are three consistent and reliable witnesses that corroborate the authenticity of the person and work of Jesus Christ, the Son of God, the One having been sent by the Father. This is John’s objective in all of his writings, to provide the definitive foundation that others may believe in Christ for eternal life:
But these have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name. (John 20:31)
John enumerates these three witnesses: the Spirit, the water and the blood. It should be noted that the Holy Spirit is a genuine person, but the water and the blood are not, yet John personifies them as equal witnesses with the Spirit. The identification of three witnesses recalls the requirement from the Law handed down to Moses, at first instructed in Numbers 35:30 that “no person shall be put to death on the testimony of one witness” (cf. Deuteronomy 17:6). It was expanded upon in Deuteronomy 19:15 as a general guideline for resolving disputes, ruling that “on the evidence of two or three witnesses a matter shall be confirmed.” This directive is emphasizes throughout the New Testament: Matthew 18:16; John 8:17-18; 2 Corinthians 13:1; 1 Timothy 5:19; Hebrews 10:28. Thus, John supplies us with the prescribed three witnesses required to disprove the Gnostic heresy, stating adamantly in verse 8 that these three witnesses are in absolute “agreement.” The Greek states that literally they are indivisibly united as one, making them legitimate witnesses.
Their Agreement
The Holy Spirit bears witness of Christ throughout this age concerning His divine works and righteousness and He will ever glorify Him (John 15:26; 16:8-14). He is the Helper and power source for the believer today (Acts 1:8; Romans 15:13). The water refers to the beginning of Our Lord’s earthly ministry—His baptism, attended by His Father and the Holy Spirit (Luke 3:22). The blood indicates the culmination of His divine mission—His crucifixion, the accomplishment of salvation for all mankind (John 17:4; 19:30).
Collectively, the Spirit, the water and the blood eternally testify to the reality that Jesus Christ was indeed the beloved Son of God. As God, having been sent by the Father to earth in the form of man, He fulfilled the divine will of His Father (John 6:38; Luke 22:42).
