[I am writing about] what existed from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and touched with our hands, concerning the Word of Life [the One who existed even before the beginning of the world, Christ]—

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].

If we say we have no sin [refusing to admit that we are sinners], we delude ourselves and the truth is not in us. [His word does not live in our hearts.]

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].

The one who loves and unselfishly seeks the best for his [believing] brother lives in the Light, and in him there is no occasion for stumbling or offense [he does not hurt the cause of Christ or lead others to sin].

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.

Whoever denies and repudiates the Son does not have the Father; the one who confesses and acknowledges the Son has the Father also.

As for you, let that remain in you [keeping in your hearts that message of salvation] which you heard from the beginning. If what you heard from the beginning remains in you, you too will remain in the Son and in the Father [forever].

Everyone who practices sin also practices lawlessness; and sin is lawlessness [ignoring God’s law by action or neglect or by tolerating wrongdoing—being unrestrained by His commands and His will].

You know that He appeared [in visible form as a man] in order to take away sins; and in Him there is [absolutely] no sin [for He has neither the sin nature nor has He committed sin or acts worthy of blame].

No one who abides in Him [who remains united in fellowship with Him—deliberately, knowingly, and habitually] practices sin. No one who habitually sins has seen Him or known Him.

The one who practices sin [separating himself from God, and offending Him by acts of disobedience, indifference, or rebellion] is of the devil [and takes his inner character and moral values from him, not God]; for the devil has sinned and violated God’s law from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.

No one who is born of God [deliberately, knowingly, and habitually] practices sin, because God’s seed [His principle of life, the essence of His righteous character] remains [permanently] in him [who is born again—who is reborn from above—spiritually transformed, renewed, and set apart for His purpose]; and he [who is born again] cannot habitually [live a life characterized by] sin, because he is born of God and longs to please Him.

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 the love of God was displayed in us, in that God has sent His [One and] only begotten Son [the One who is truly unique, the only One of His kind] into the world so that we might live through Him.

In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation [that is, the atoning sacrifice, and the satisfying offering] for our sins [fulfilling God’s requirement for justice against sin and placating His wrath].

No one has seen God at any time. But if we love one another [with unselfish concern], God abides in us, and His love [the love that is His essence abides in us and] is completed and perfected in us.

We [who were with Him in person] have seen and testify [as eye-witnesses] that the Father has sent the Son to be the Savior of the world.

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

If anyone says, “I love God,” and hates (works against) his [Christian] brother he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.

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.

If we accept [as we do] the testimony of men [that is, if we are willing to take the sworn statements of fallible humans as evidence], the testimony of God is greater [far more authoritative]; for this is the testimony of God, that He has testified regarding His Son.

The one who believes in the Son of God [who adheres to, trusts in, and relies confidently on Him as Savior] has the testimony within himself [because he can speak authoritatively about Christ from his own personal experience]. The one who does not believe God [in this way] has made Him [out to be] a liar, because he has not believed in the evidence that God has given regarding His Son.

And the testimony is this: God has given us eternal life [we already possess it], and this life is in His Son [resulting in our spiritual completeness, and eternal companionship with Him].

He who has the Son [by accepting Him as Lord and Savior] has the life [that is eternal]; he who does not have the Son of God [by personal faith] does not have the life.

These things I have written to you who believe in the name of the Son of God [which represents all that Jesus Christ is and does], so that you will know [with settled and absolute knowledge] that you [already] have eternal life.

If anyone sees his brother committing a sin that does not lead to death, he will pray and ask [on the believer’s behalf] and God will for him give life to those whose sin is not leading to death. There is a sin that leads to death; I do not say that one should pray for this [kind of sin].

All wrongdoing is sin, and there is sin that does not lead to death [one can repent of it and be forgiven].

We know [with confidence] that anyone born of God does not habitually sin; but He (Jesus) who was born of God [carefully] keeps and protects him, and the evil one does not touch him.

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.
