1 John 5:6-13 - The Certainty Of God's Testimony
6 This Jesus is the one whose coming [to earth was introduced] by water [at His immersion. See Matt. 3:13] and [completed] by blood [at His crucifixion, John 19:17-37]. He did not come by the water only, but by the water and by the blood. And it is the Holy Spirit who gives testimony [at both of these events], because the Holy Spirit is [always] the truth. [See John 16:13]. 7 For there are three who give their testimony [about Jesus]: 8 The Holy Spirit [through His Word], and the water [through His immersion] and the blood [through His crucifixion]; and these three agree together [in giving testimony about Him]. 9 If we [are willing to] accept the testimony of people about matters, [surely we ought to accept that] the testimony of God is more reliable; because the testimony of God is that He has presented [confirming] testimony concerning [the identity and mission of] His Son. 10 The person who [sincerely] believes in God's Son has the evidence [of it] within his heart, [confirming God's testimony]. The person who does not believe God [i.e., what He says about Jesus], accuses Him of lying, because he has not accepted the [irrefutable] testimony of God concerning [the identity and mission of] His Son. 11 And this is the testimony [of God]: He gave to us [the hope of] never ending life, and this life is [available through fellowship] in His Son.
12 The person who has the Son [in his heart] possesses this "life;" the one who does not have the Son of God does not possess this "life." 13 I have written these things to you people, who believe in the name [i.e., in the person and work] of the Son of God, so that you can have assurance that you have [the hope of] never ending life. [See Titus 1:2; 3:7; Mark 10:30].
