Notes on 1 John 5:6-21

<< Previous Note(s)1 John Main PageNext Note(s) >>

Water and blood - 1 John 5:6

water and blood. See BC 34. See note on 4:13. In Greek mythology, the gods of Olympus did not have blood, but ichor, a watery substance. It is likely that those who left John's congregation recognized Christ's deity, but not his humanity. This reference to water and blood shows Jesus Christ was both God and man. In his Gospel, John uses the words by water three times in reference to John the Baptist (see notes on Jn. 1:26, 31, 33). Therefore, it is possible John is referencing Jesus' baptism with water at the beginning of his ministry, and the end of his earthly ministry with blood that references his crucifixion

Testimony of God - 1 John 5:9

testimony of God. See WCF 1.4. Because of the Spirit's part in the three witnesses, John identifies the source of this testimony as God. John's argument is from the lesser to the greater. If we accept human testimony, how much more should we accept God's testimony.

1 John 5:10-12

See WCF 14.2; WLC 32; BC 21; HC 61

A liar - 1 John 5:10

in himself… a liar. John provides yet another group of three witnesses: the Father, the Spirit and the believer. At the baptism of Jesus, the Spirit's descent on Jesus and the Father's voice both show that Jesus is the Son of God. The two testimonies always work together (see notes on Mk. 1:1; 15:39; Jn. 20:31). When a person believes that Jesus is the Messiah, they not only receive this message, they also receive the anointing of the Spirit (see notes on 1 Jn 2:20-27). To refuse these two sets of three witnesses, who attest that Jesus is the Messiah is to call God a liar (see note on 1:10)

Eternal life in his Son - 1 John 5:11

eternal life… in his Son. God's testimony about Jesus includes the benefits of his reign as Messiah to his people, namely eternal life. Risen from among the dead, Jesus is both alive and the life-giver (see note on Gal. 2:20). Eternal life is not the mere extension of this life, rather, it is life as the Messiah secures, cultivates and shares it

Does not have the Son - 1 John 5:12

does not have the Son. See WCF 10.3. Based on John's Gospel, to have the Son means to abide or remain in Christ (see notes on Jn. 6:56; 14:23; 15:4-7). The Father has eternal life in himself, and he gives it to those who believe in Jesus. God's Son, gives God's Spirit to those who believe God's testimony about the Son. Those who have the Son know the Father and the Spirit, but those who do not have the Son do not know God.

Assurances of Eternal Life - 1 John 5:13-21

The Witness' Concluding Assurances of Eternal Life. John summarizes the argument of his sermonic letter, giving some final assurances and instruction. First, vv. 13-15 articulate John's overall purpose for writing. Second, vv. 16-17 give instructions about how to pray for those around them, whose sins do not lead to death. Third, vv. 18-20 reassure John's readers that they are under the authority of Jesus, not the power of the evil one. Verse 21 is a final word, a strong exhortation against idolatry, a sin that leads to death.

1 John 5:13-15

See WCF 21.3-4; WLC 180, 184, 186; WSC 98-99; BC 12; HC 117.

So that you will know - 1 John 5:13

so that you will know. See WCF 18.1, 3; WLC 80; 172; WSC 36. Repeatedly, John has referenced this purpose for writing—to assure his readers that they know God. Often, he employs verbs for knowing in this short letter: oida (2:11, 20-21, 29; 3:2, 5, 14-15; 5:13, 15, 18-20) and ginōskō (2:3-5, 13-14, 18, 29; 3:1, 6, 16, 19-21, 24; 4:2, 6-8, 13, 16: 5:2, 20). Uniquely among the evangelists, John says Christ's followers will not only possess eternal life in the future, they also experience it now, because they already enjoy fellowship with God (see notes on 1:3-4; Jn. 17:3). This assurance of true knowledge arises from a true confession of Jesus as the Messiah, obeying him and loving your brothers and sisters in your words and deeds.
