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]!

If we claim that we have not committed sins, we are [in effect] calling God a liar [i.e., because He says we have] and His word [i.e., the real truth about the matter] is not in our hearts.

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].

I have written to you little children [i.e., dear ones], because you have known the Father [as your God]. I have written to you fathers, because you have known Him [i.e., Christ], [who has existed] from the beginning. [See verse 13]. I have written to you young men, because you are [spiritually] strong and the word of God continues to live in your hearts, and you have overcome the [power of the] evil one [See verse 13].

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].

No one who has been [spiritually] conceived [and eventually born] by God continues to live a sinful life, because God's seed [i.e., His word, See Luke 8:11] continues to live in his heart, so he cannot [continue a life of] sin, because he has been conceived by God.

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].
