We [apostles] proclaim to you [the truth about Jesus], who existed from the beginning [of time]. We have heard [Him] and seen [Him] with our [own] eyes. We looked at Him, and [even] touched Him with our hands. [See John 20:20]. [So, we proclaim that] He is the word of life [i.e., the life-giving Word]!

We declare to you what we have seen and heard [concerning Christ], so that you also may share a relationship with us. And indeed, our fellowship is with the Father and with His Son Jesus Christ.

But, if we live in the light [of righteousness] just like God [constantly] lives in the light [of righteousness], we can truly share a relationship with one another and [can know that] the blood of Jesus, God's Son, continues to cleanse [our spirits] from all of our sins.

My little children [i.e., dear ones], I am writing this to you so that you will not sin anymore. But if anyone does sin, we have Someone to go to the Father on our behalf; it is Jesus Christ, the [only] righteous One.

And here is how we can be assured that we know Jesus [i.e., that we are saved]: [It is] by obeying what He commands us.

The person who claims he is continuing to live in [fellowship with] Jesus should also live the way He did.

My dearly loved ones, I am not writing to you about a new commandment, but about an old one. [It is the one] you had learned about from the beginning. [Note: This is the commandment to love one another (3:1: II John 5) which Jesus had taught his disciples during His earthly ministry. See Mark 12:31]. This old commandment is the word [of God] which you heard [previously].

Yet, I am [also] writing to you about a new commandment [Note: This commandment was to love one another as Jesus loved them. See John 13:34]; its truth is [being demonstrated] by Christ [perfectly] and [also] by you people [in a lesser measure], because the darkness [of sin] is passing away, and the real light [of righteousness] is already shining [in people's lives].

But, you people have a "special gift" from the Holy One [Note: The Greek word for "special gift" is "charisma" and probably refers to the Holy Spirit (See Acts 2:38); "Holy One" probably refers to Jesus, (See Acts 2:27; 3:14)], and all of you know [the truth].

Who is the liar? It is the person who denies that Jesus [truly] is the Christ [i.e., God's specially chosen One]. This person is the antichrist [See verse 18]; he is the one who denies [the truth about] the Father and the Son.

Dearly loved ones, we are God's children now, but it has not yet been revealed [to us] what we will be [in the future life, Luke 20:34-36]. But, we do know this, however, that when Jesus is revealed [i.e., at His second coming], we will be like Him [I Cor. 15:49], for we will see what He really looks like!

And every person who has set his hope on this [i.e., of being like Jesus], will live [as] purely [as possible], just as He [i.e., Jesus Himself] is pure.

Here is how we can know what genuine love really is: It was [demonstrated by] Jesus laying down His life [on the cross] for us. And [because of that] we [too] should [be willing to] lay down our lives for [the sake of helping] our brothers [and sisters].

And this is His commandment: We should believe in the name of His Son Jesus Christ [i.e., the person of Christ], and love one another, just He has commanded us to do.

Here is how to know [who is speaking from] the Holy Spirit of God: Every spirit [i.e., person] who proclaims that Jesus Christ has come [to earth] in a physical body is [speaking] from God. [See I Cor. 12:3].

But every spirit who does not proclaim [this truth about] Jesus is not [speaking] from God. And this [person] represents the spirit of the antichrist [See 2:18-22; II John 7], whom you have heard would come. Well, now he is already here!

Whoever proclaims that Jesus is the Son of God, God [continually] lives in that person's heart, and he lives in [fellowship with] God [See 2:23].

Here is what a complete love will do for us: It will give us boldness in [facing] the judgment day, because the way Jesus acts [regarding love] is the way we should act [while] in this world.

Every person who believes that Jesus is the Christ [i.e., God's specially chosen one] has been [spiritually] conceived [and eventually born] by God. And everyone who [continually] loves God, who did the conceiving, also [must continually] love the person whom God has [spiritually] conceived.

And who is the person who can overcome [the evil influence of] the world? [It is] the one who [truly] believes that Jesus is the Son of God.

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].

For there are three who give their testimony [about Jesus]:

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.

And [in addition], we know that the Son of God has come [in a physical body, See 4:2] and has given us understanding, so that we can know the True One [i.e., God], and that we are in [fellowship with] the True One, even His Son Jesus Christ. This Son is the true God and eternal life.
