what we have seen and heard we also proclaim to you, so that you too may have fellowship [as partners] with us. And indeed our fellowship [which is a distinguishing mark of born-again believers] is with the Father, and with His Son Jesus Christ.

but if we [really] walk in the Light [that is, live each and every day in conformity with the precepts of God], as He Himself is in the Light, we have [true, unbroken] fellowship with one another [He with us, and we with Him], and the blood of Jesus His Son cleanses us from all sin [by erasing the stain of sin, keeping us cleansed from sin in all its forms and manifestations].

My little children (believers, dear ones), I am writing you these things so that you will not sin and violate God’s law. And if anyone sins, we have an Advocate [who will intercede for us] with the Father: Jesus Christ the righteous [the upright, the just One, who conforms to the Father’s will in every way—purpose, thought, and action].

And He [that same Jesus] is the propitiation for our sins [the atoning sacrifice that holds back the wrath of God that would otherwise be directed at us because of our sinful nature—our worldliness, our lifestyle]; and not for ours alone, but also for [the sins of all believers throughout] the whole world.

Who is the liar but the one who denies that Jesus is the Christ (the Messiah, the Anointed)? This is the antichrist [the enemy and antagonist of Christ], the one who denies and consistently refuses to acknowledge the Father and the Son.

This is His commandment, that we believe [with personal faith and confident trust] in the name of His Son Jesus Christ, and [that we unselfishly] love and seek the best for one another, just as He commanded us.

By this you know and recognize the Spirit of God: every spirit that acknowledges and confesses [the fact] that Jesus Christ has [actually] come in the flesh [as a man] is from God [God is its source];

and every spirit that does not confess Jesus [acknowledging that He has come in the flesh, but would deny any of the Son’s true nature] is not of God; this is the spirit of the antichrist, which you have heard is coming, and is now already in the world.

Whoever confesses and acknowledges that Jesus is the Son of God, God abides in him, and he in God.

Everyone who believes [with a deep, abiding trust in the fact] that Jesus is the Christ (the Messiah, the Anointed) is born of God [that is, reborn from above—spiritually transformed, renewed, and set apart for His purpose], and everyone who loves the Father also loves the child born of Him.

Who is the one who is victorious and overcomes the world? It is the one who believes and recognizes the fact that Jesus is the Son of God.

This is He who came through water and blood [His baptism and death], Jesus Christ—not by the water only, but by the water and the blood. It is the [Holy] Spirit who testifies, because the Spirit is the truth. [He is the essence and origin of truth itself.]

And we [have seen and] know [by personal experience] that the Son of God has [actually] come [to this world], and has given us understanding and insight so that we may [progressively and personally] know Him who is true; and we are in Him who is true—in His Son Jesus Christ. This is the true God and eternal life.
